documents: #Person1#: Hi, Don. Would you like to go swimming this afternoon?
  #Person2#: I wish I could, Jenny, but I have to spend the rest of the day in the library. I have a ten-page paper due tomorrow.
  #Person1#: Oh, is that for Professor Smith's class?
  #Person2#: Yes, I have to write an article on a poem we read in class.
  #Person1#: That's hard. How is it going so far?
  #Person2#: Not very well. And I also have to study a lot for maths and history. I don't know how I'm going to do it at all.
  #Person1#: You know, Don. I've been doing well in maths, so I'd be happy to help you.
  #Person2#: OK, Jenny, I'll see you in front of the library.
  #Person1#: Good luck with the poem.
