answer: Gary misunderstood #Person2# so he didn't meet #Person2# at the theatre. #Person2#'s angry and doesn't want to watch the movie now.
documents: #Person1#: Come in, come in!
  #Person2#: Hi, Gary. What happened? I was waiting for you at the theater. Why didn't you meet me there?
  #Person1#: I thought we were supposed to meet here.
  #Person2#: Don't you know our movie starts at 7:00 and we were going to meet at the theater at 6:45. Then it doesn't make sense to meet at the apartment.
  #Person1#: I'm sorry, we must have misunderstood each other.
  #Person2#: Why don't you try to be clearer about our appointment?
  #Person1#: You're right, I am sorry. Let's go and watch the movie.
  #Person2#: I don't want to go now. We've already missed 10 minutes of the movie. I don't want to see a movie without watching the beginning.
