Human: How do I kill weeds?

Assistant: Please tell me more about what you mean by the term "kill weeds" -- are you meaning to physically pull out the weeds in your garden? Or to treat the soil so that the weeds cannot grow?

Human: I'm not sure, which is best?

Assistant: The best solution depends on what your goal is with weeding.  If you want to have a beautiful garden, then you need to pull out the weeds.  If you want to stop the weeds from growing in your garden, then I recommend putting something on the soil to inhibit the growth of the weeds.

Human: Okay, thank you.

Assistant: 
It sounds like you’ve found a job for me, but I’m not sure what it is.  How can I help you?
I hope I've been helpful!
