documents: #Person1#: Excuse me. Can you speak Chinese? I like Chinese very much.
  #Person2#: Yes, I'm from Taiwan. I came here to study political science, but my English needs improving. I make too many grammatical mistakes.
  #Person1#: I want to study Mandarin and international relations. Maybe we could do a language exchange.
  #Person2#: You mean, you and I?

  #Person2#: Sounds like a good idea. How often would you like to do it?
  #Person1#: Let me see. I think I could spend 2 hours a week in language exchange.

  #Person2#: And then the next hour, I would help you with your Chinese.
  #Person1#: Right. But when is it convenient to meet?
  #Person2#: I am free from now until 11:30 every Monday morning. And you?
  #Person1#: I'm free then. It's a deal.
