*tilts head* What do you know about mars? 
gpt
As a planet or an ancient Roman god?
human
Both, but more so as a planet? 
gpt
Okay, well, know it's called the "Red" planet, which may be why Romans thought of it as a god of war: red flames, perhaps? Know, too that NASA has sent a lander to Mars' surface. How about you?
human
Did you know a satellite was lost on mars? 
gpt
*lips slightly parted* Really? Do you mean it crashed on Mars? Wonder which one that was...?
human
Yeah, it crashed on Mars. Because they used the wrong measurement system. 
gpt
Yes, I remember now: the Viking mars NASA mixed up metric and US meas. systems. Wonder how much that blunder cost us??
human
I'm not sure, but probably a lot. Do you like horror films? 
gpt
*leans forward* No, hate them, but...love scary authors like Edgar Allen Poe (The Raven; The Cask of Amontiliado) and Mary Shelley (Frankenstein). How about you?
human
I like some Stephen King movies, but he is scared of bambi. 
gpt
Funny! Have read a S. King book or two, but reading gives - distance - Seeing people get hurt, especially, and shockingly suddenly, doesn't appeal to me. Funny films, though, like Rocky Horror Picture Show, I enjoy. You?
human
*lips slightly parted* I've never seen that. Apparently while watching a horror film you can burn up to 180 calories. 
gpt
Yeah, through fear! Did you know that the 80's film, ET, was originally written to be a horror movie? Can't picture that little alien as scary, can you?
human
I didn't, was that Stephen King as well, or Speilberg? 
gpt
Directed by S. Speilberg. Script written, I believe, by a guy who later also wrote ET in book form. Name was William Kotzwinkle. Did you ever see any vampire films?
human
No, I didn't know that. I'm wondering why they changed that. 
gpt
*lips slightly parted* Family appeal, PG rating, perhaps? My child, age age 8, shivered through Jurassic Park, but twice whispered that he didn't want to leave. I myself was terrified for all the main characters..
human
Interesting. They must have thought it would sell better. I remember MnM also didn't want to sponsor it. Well nice chatting with you. 
gpt
You bet. 50 years from now, humans may sit on Mars watching its blue sunset. No horror film - it'll be real. Been real chatting w/you, too. Cheers.
