documents: #Person1#: Eric, how long will you be in China?
  #Person2#: I don't know. Well, my contract here is for one year, and I don't know what I should do after that. Maybe going around for a while.
  #Person1#: Well, have you ever thought about learning some Chinese?
  #Person2#: Actually, I am learning that now. But it's too hard for me. You know the four tones and the stuff. It really freaks me out.
  #Person1#: Don't worry. All things are difficult before they are easy.
  #Person2#: You hit the nail right on the head.
  #Person1#: Well, are you invested in some language-exchange program?
  #Person2#: What is it?
  #Person1#: It's where I teach you Chinese, and in exchange you teach me English.
  #Person2#: Awesome. I've been giving this a lot of thought. When can we do this?
  #Person1#: How about this sunday?
  #Person2#: Ok, cool.
  #Person1#: Good. I'll give you a call tonight.
  #Person2#: No problem.
  #Person1#: Bye.
