answer: Tom invites #Person2# to do Chrismas shopping on Friday night, but #Person2# isn't sure if #Person2# will be available. Tom gives #Person2# his contact information and #Person2#'ll tell him then.
documents: #Person1#: It's almost Christmas. What are you doing this weekend?
  #Person2#: Nothing special, just working. Why do you ask?
  #Person1#: Well, I still haven't finished my Christmas shopping. Do you want to go shopping with me this weekend?
  #Person2#: I'd like to, but I'm not sure if I can. Work has been really busy lately. Why don't we go on Friday instead?
  #Person1#: Friday's not good. I think the stores will be very crowded and I have to work.
  #Person2#: OK, then let's try to go this weekend. I should know if I can go by Friday. Is it OK if I call you then?
  #Person1#: Yeah, that's fine.
  #Person2#: What's your number?

  #Person2#: OK, I'll talk to you soon.
  #Person1#: OK.
