documents: #Person1#: Hello?
  #Person2#: Hello, Bob? This is Nancy. I got the invitation yesterday.
  #Person1#: Oh, can you come?
  #Person2#: Yes, I think so, but Tony can't. He's got to go to his parents' and help them work on their house this weekend.
  #Person1#: Oh, that's too bad.
  #Person2#: Uh, Bob. I won't have any transportation that night. Think somebody could give me a ride?
  #Person1#: Oh, sure! There's a group of people coming who live near you. I'm sure one of them would be glad to. If that doesn't work out, I'll drive you.
  #Person2#: Great! Thanks, Bob. Uh, what will people be wearing?
  #Person1#: Oh, you needn't dress up. It's a fairly casual party. We'll be in the yard, you know.
  #Person2#: Good. I can wear my new pants and sweater. Uh, what can I bring?
  #Person1#: Well, a side dish would be good. There'll be plenty to drink.
  #Person2#: OK, see you then.
  #Person1#: Bye!
