answer: #Person1# asks #Person2# whether #Person1# can smoke inside and #Person2# refuses. They don't agree with each other's suggestions.
documents: #Person1#: Do you mind if I smoke here? 
  #Person2#: Yes, I do. I'd prefer you didn't. The AC (air-conditioning) is also on. 
  #Person1#: Can I just turn off the AC for now and open the window and smoke indoors? 
  #Person2#: That's not a very good idea. It's quite hot outside. Why don't you smoke outside? 
  #Person1#: It's very hot and that's why I'd like to smoke inside. 
  #Person2#: Though the AC has the air-purifying function. I'd still rather have fresh air than smoke. Are you okay with that? 
  #Person1#: Oh, no problem.
