answer: #Person1#'s trying to organize a group to play at some parties on weekends. #Person1# invites Robert to play the guitar, and Robert says he'll have a try.
documents: #Person1#: Robert, you play the guitar, don't you?
  #Person2#: I used to. But I haven't played it for quite some time. I don't really have time these days with all my studies. Why do you ask?
  #Person1#: I'm trying to organize a group to play at some parties on weekends. We still need a guitar player.
  #Person2#: Well, I don't know. But your idea sounds fun to me.
  #Person1#: Oh, it will be. I'm more or less in charge of things. So if you want to give it a try, you're in. It's as easy as that. Besides, it's a great chance to get out and meet people.
  #Person2#: But I told you I haven't practiced for a long time. I don't know if I remember any songs I used to play.
  #Person1#: Don't worry about it. I just thought I'd ask you to try and join us sometime when we were practicing. We'll be practicing for a few months before we give performances.
  #Person2#: OK, I'll have a try.
  #Person1#: I'm sure you can do it. And it will be fun, too.
