documents: #Person1#: Hello?
  #Person2#: Hello, Mary?
  #Person1#: Hello, George.
  #Person2#: What are you doing on Tuesday night? There's a great show at the Varsity Theater.
  #Person1#: Tuesday night? Oh, sorry, I'm planning to finish my term paper. It has to be in on Wednesday morning.
  #Person2#: Oh, well, never mind. Look, Wednesday, why don't we go out for dinner. We could go to that little restaurant you like so much.
  #Person1#: That sounds like a great idea, but I think I might have to help my roommate clean the apartment. You see, we are having some people over on Thursday night, so we want the place to look really nice.
  #Person2#: Well, that means you're going to be busy Wednesday night too?
  #Person1#: I'm afraid so.
  #Person2#: Well, how about Friday night? There's going to be a basketball championship at school. How about we go and root for the old Blues?
  #Person1#: Yes, I was planning to see that, but you know what's come up -- it's Daddy's birthday, so we are taking him out for dinner.
  #Person2#: Well, what about Saturday night?
