Okay guys. So how's everyone today? The weather's beautiful like we had discussed. So it's hard to be bad on a day that feels like this, I think, right? I love this breeze. Can you guys feel that? Can you feel the breeze? It feels amazing. It's better than the air conditioning for Vince, right? It's quiet and it feels better and it's cleaner. Do we want the air conditioning and the window open? No, I'm confused. All right. So today when I was on my way here, I was beginning to tell you, I was texting my friend. I have this friend. Every time I text him, he does not answer. He may answer me like three days later. What do you do? That too. That's a good example. That too. Does that ever happen to you? So you think that maybe he was hoping he did not answer? That's a good idea. Those are good suggestions.  When you try, whether it's your children or your... Why is that? Very good, eh? Yeah? It's frustrating? So why do you think they don't answer? They don't answer, but they keep in silence. So they say, oh, they are meeting with their friends. They are texting with other people. And they say, oh, it's mommy now. So it can't be anything else. It must be that they are maybe ignoring? So you must answer, but not them. But the American has his feelings. Yeah, how does it feel? Maybe you should try it. Abdul, does that ever happen to you? That doesn't sound fair. So why do you think he doesn't answer? So he must be busy, you think? Or is there a chance maybe he is doing something else or he must be busy? So if he doesn't answer, do you think that he must be busy? Or maybe something else? Okay, so yeah, I have a friend, and then Vince, you said as well at first, right? Really? They don't like it? Hmm, why is that? So maybe they are driving, and that is why they like the phone calls? Or that they prefer the phone calls? Or that they prefer, yeah, so then why, yeah, good point. So why then, if they are driving, they should not be texting, right? Okay, Bluetooth is safest, I think. Okay, you can buy something, I think, for that though, right? Yesterday I cut a red light, but because I turned it on right, you can't hear. If it does not say no turn on red, right? But most of the time you can turn on the right, and the police officer just stops in the middle of the line, and I thought I cut on the right, no problem. Really? So you did both in one try? Very good, that's funny. So France, yeah, so is that weird for you to see everyone turning on red lights and on the phone? It's very different? Yeah, here everyone is on the phone. Do you notice a lot of people on the phone when you drive? Right? All of them? Oh, 95 especially, right? That same lady that you see?  So if I wrote this sentence, Tony is not home, he blank be at the gym. What do you think I could fill this with then? Might, right? Might? Is there another word you can think of? Okay, might or may, very good, very good, right? Yeah, so those all fit, he might be at the gym. Why would we say might here? We don't know, right? So maybe, very good. So why, what else would you say? Maybe he's, why would you say might or may? Because we don't know, and he could be, what do you think? Very good, yeah, right? So if he's not at home, like you said, he might be at the gym, but he might not be at the gym, right? So those, have we heard of what this is called, like the might and may? Very good, models of deduction, so might and may, right? So that's when we don't know. What do you know, what is it when we, when we do know? What is the model of deduction when we do know? Must, very good. So you guys have seen this before? So must, must, so we do know must then? So we said might and may is when something is, is possible, but, but we're uncertain. And you said, now what did you say must was? Very good, so when you are sure, right? Very good, when you are sure. So if I say, and then you said that if someone is, is not, if you think that it is not possible, what was that? If I said, ah, very good, can't, can't, that's not possible. So can we use must in a sentence? Can you use must in a sentence, an example sentence? The word must, uh-huh, you must, you must turn right. You must turn right when the road is free. But you, you, it's not that you must turn right because you can go left, right? So would that be more of another one maybe? He did give you a ticket. Oh, okay. Siren or badge? Yeah, and he was, he opened the door and he was coming and I was just, he might have moved a little bit and I moved and he just closed the door and he walked. You got lucky. You got lucky. So the, so can we use must in a sentence? Can we think of another sentence? Any sentence just with the word must? So if you are in the right turn lane you must turn right. Okay, very good. And then what about can't? What about can't? Ah, very good. So we keep it the same, right? We keep it the same. So, you know, that blue car can't be his car because his car is white, right? So that's impossible. It's impossible. And then, and then the other one would be might in May. Like, can we think of another one with might in May? Okay, so someone might turn if they have the opportunity. Very good, very good. So you guys, so you guys are pretty comfortable with this stuff. The might, the may, the must and the can't. So those are models of deduction. So we've seen that before? Great. All right guys, so I brought in a, today I brought in a worksheet and it's a, it's a funny worksheet. I'll show it to you guys. I did this in pairs of two and, and it works with what we just did. So right before I hand it out, let me just tell you, I'll give you an example. So, if you can see here, there's six people here. And what you are going to do is you are going to try to match the job with the people. So, you might say that number one is a boxer. So that there's a list here. Boxer, hairstylist, politician, psychoanalyst, university professor, and violinist. Okay, do we know what all of those are? All of those jobs are? Okay, great. So, then we say what, we eliminate the jobs that they are not. So, you might say this guy can't be a politician. And then the second one, you say what are possible, right? So, if it is possible, then which one will we use? We would use, might or may, right? So, then we would say what they might is possible. And then the next one would be what our final choice, what they definitely, we think, what we think they definitely are. So, then what will we use there? Must. Must, right? Very good. So, it's kind of funny. I'm going to pass this out here, and then we can go through. I'm curious to see what you guys think. I have the answers which I will give you at the end, so I will tell you what they really do and who they really are. But just by looking at them, you can kind of try to match them up. So, again, what they can't be, what they might be, and what they, we think that they must be, right? So, we'll take a few minutes to do that, and then we will go over it and review. And see if everyone agrees or we have different answers. Does anyone know what a politician is? He's technically a politician. What do you guys, how would you define a politician? What is a politician? Yeah. So, someone who works with the government would be a politician. But in that, in like the government sector, of the governmental like political section, like you're seeing a lot on TV right now, right? Politician? I don't think they need to be elected. I think they just, they work with the political section of the government, right? Any other ideas on Abdul? Are you familiar with politicians? Yes. A little bit? What would you say? Okay. You would say he used to be a politician. Yes, he used to be. Hmm? You would say he used to be a boxer. Used to is when you usually did something and then you stopped. So I would say, if I stopped eating ice cream, I would say I used to eat ice cream, but now I don't. So he used to be a boxer, but now he, or, yeah, very good, isn't it? Yeah. Five years ago I was a teacher. Okay. Now I'm a geologist. Yeah, that's fine. You said I used to be a teacher. Well, you said I was in your last example and that's fine. Yeah, you could say I was a journalist and now I am a teacher. Yeah. Really? You've never heard of that? For example, I'm using my phone. Using, right?  U-S-E-D. U-S-E-D and then to be, right? Used to be a politician. Yeah. Very good. Yeah. So how are we doing on the exercise? It's actually hard. Once I give you the answers, you will be surprised. How are we doing? There are answers. Yes, I had said in the beginning, I will give you the answers. They are real people and they have real positions. And those are their real positions. So I will give you their names, who they really are and what they really do. No, no, no. Maybe not. Maybe. She may surprise you. Maybe. You say she must be the boxer? No, she might. Might or maybe? Who can't be the boxer? Who is he? The hairstylist? Because you like his hair? No, because... Feminine? I don't know. I don't want him to get mad at me. How's it going over here? Oh, you guys have it down to a science. You guys are doing math over here. If you carry the two and minus the one, divide by three and that is the boxer. So I'll give you guys a few more minutes. Psychoanalysts? It's like a psychologist. They analyze you. Do you know the word analyze? It's not exactly the same, but that's what they do. They analyze you psychologically. They would look at that.  Very good. Yes, exactly. Yes. Do you see it as half full or half empty? Half full, half full? Do you guys see it as half full or half empty? Half full. Very good. That's a good way to look at life. It's full, right? Or is it one quarter empty? All right, so let's get back to the worksheet. So what did we get for the first one there? What do we think someone can't be? So if they can't be something, then what are we doing? But if they can't be something, that means that they, what? So are you saying that he can't, that he is or he is not? He can't. So he is not? I think he is not a journalist. He is not what? A journalist. What? Which one? The first one. The first one is not a journalist? What do you guys think? Not a journalist. He can't be. He can't be. You think he must be a politician? No. So what do we think? No. Maybe? Okay. What do you think he may or might be? He used to be. Oh, so that's why you were asking. Okay. He's a little older. So what about the second one? What do we think of him? So you think he must be? Yeah. A hairstyle? Yeah. Okay. But he can't be a boxer. Okay. What do you guys think of the second one? Okay. Can't be a boxer. Can't? Okay. Why? He must be a boxer. Wait, he must be a boxer? Number two? No. Okay. Okay. Okay. He can't be? No. He might be? Okay. He might be? That's fair. Yeah. Okay. So we have different answers. This will be surprising. What do we think of three? What do you guys think? Okay. Can't be a boxer. What might or may it be? What did you have for the first for B there? What is he not? So using the models of deduction you would say his hair does look a little crazy, huh? And what about the... Okay, very good. You're right. And what did you guys think? So we all agree that he can't be a hairstylist. Okay. So what about five? Do you think she could be a hairstylist? She has nice hair. She must be a hairstylist. Or what else? He does it though. Hair stylist? Okay. So we agree on that one. We agree on that one and the one before. All right. So now the last one. So now what must she be? What do we think? She can't be? Be a boxer or can't? So she must be a boxer. So a boxer you would say? Is that what you said? Oh, no. She must be a politician. Okay. And then she may or can't be a... What do you guys think of the last one? Are you guys ready for the answers? Because it's a little different than what you thought. So the answer to number one. His name is Vince Cable. He is a politician. He is a politician. So we were on the right track with that one a little bit, right? And you guys had that one. Number two, his name is Richard Ward. Hair stylist. So I think you both got that one. I think you both did that one correctly, right? Sure. So three is Mary Beard. She is a university professor. So you guys were actually pretty good with this. Number four. Number four, Adam Phillips is his name. He's the psychoanalyst. Five is Nicola Benedetti. She's a violinist. Six is Nicola Adams. And she is a boxer. But you had them down the boxer, but then you said... I think you said she must be a boxer. So she had it. Very good. Very good. Which one was the most confusing there? At the same time, you did pretty well just looking at pictures, I think, right? So now I was thinking of actually putting this concept of the models of deduction into a little activity. So have you guys ever used air, B and B? What is that? Okay. Any other information or explanation? Okay. Has anyone used it before? Okay. And did you like it? So that's what it is, exactly. You can, instead of booking through a hotel, you can rent someone's apartment or house. Okay. So what I was thinking is we make an imaginary apartment or house or villa that we are going to rent.  That's basically everything. Yeah. Exactly. So what you will do is you will write that information. This is where it is. This is who I am. This is... Yeah. But you will say these are the things that you may or might want to do in the area. You may want to go to... If it's in Florida, you may want to go to the beach. You may want to go to the Everglades. You might want to go snorkeling or scuba diving, things that you might want to do. And then what about the things that you can't do, right? Do they ever say like, you can't... Yeah. You can't smoke. Right? You can't smoke? You can come with older people. Right. You can't just... You can't come with... You can come five people. Right. Yeah. So, exactly. Yeah. Very good. So I'm curious, what rules would you have if you rented your apartment on Airbnb?  Then you might say what you might or may want to do. And then the rules. You can't do this in my house. You can't do this in my house. You might do this. You may want to do this. So they might live there and they might not. Yeah. So it depends on which one you, maybe you must live there. Maybe you can't live there. Well, that's very good. Very good. That's much cheaper than a hotel. All right. So we'll take a few minutes to try to do this and then we will go over there. I'm curious what you would charge to compare. I don't know. No, I don't know. Is it? I did not know. So then use that knowledge to, what would you, what would you charge for your room then if it was here? What? You can use that knowledge or information to choose what you would charge for your apartment here. Yeah. You know maybe you can charge, you are competing with hotels? I never. I never. And you know the prices? I never. I never. I never. I never. I never. I never. I never. I never. I never. I never. I never. I never. I never. I never. I never. So if there are any resources here so you can compare for your Airbnb, right? And you, you maybe can write I know hotels in the area are 120 and I charge plus. I think that's average. That's like the average price of a hotel around here. A little over a hundred dollars? Yeah. Well, but you're close. I mean, the only closer road with a hotel is A1A, basically. Was it nicer? Exactly. That's how it works, yeah. All right, so we'll take another few minutes, and then we will go over it. OK, you must be less noisy. You must not be noisy. That's a good rule. When do you not use it? Can you give me an example? You usually need. I went to school. Well, we usually use the when we are talking about something that we specifically know, like the dog. I saw the dog. So you must know a specific dog that I am talking about. And then we use like a dog when we don't know. Yeah, so if you say I went to the school, then I would be talking about a specific school, right? I went to school in Fort Lauderdale, I mean, it's just not specific, right? But there are circumstances where we don't use the when we do, yes. I went to school, I went to the school. That's a good rule. So what did you guys have? Tell me about your place, let's see. That seemed, that was very thorough. What did you guys think of that place? Would you stay there? No? Why not? Why not? Too strict? Too many rules? So they say you are too strict. Let's see, so let's see, let's see this party palace over here. So tell us about your place. Rules here, who owns the place? So after 10? OK, that's not too bad. OK, cannonball, can I cannonball? No guests, no guests.  What do you guys think of their place? Do you like it? No? It is a prison. So do we like it, Abdul? There is no privacy. There are cameras. OK, so the prices are very low? How much? Per night? That's kind of expensive, no? We are in Switzerland. OK, OK. So what might I do? What might or may I do? OK, so do I go to the beach? Are there beautiful beaches? Right? What beach? What beach? Oh, there's a lake. Talking about the beach along the lake. The beach along the lake. So the beach along the lake, maybe? The beach along the lake, maybe? So there's a lot to do. There's a lot that I can do. There's also a lot that I can't do. That's another rule. That's another rule. Very good. So very good, guys. So that's the end of the class. Very, very good. So we learned the models of deduction. We also learned that both of our houses on Airbnb are very strict and have a lot of rules, right? We learned what we can't do, what we must do. We must return the key. We must pay the deposit. And we learn what we may do, right? So very good, guys. So you guys have a good day. I will see you all tomorrow, OK?
