answer: #Person1# and #Person2# are talking about the types of girls they preferred. They may go to the gym together because both of them gained weight recently.
documents: #Person1#: That girl looks very attractive, doesn't she?
  #Person2#: Do you think so? I don't like girls who look like that. I like girls who are not too slim. If you like her, go and talk to her.
  #Person1#: I'd like to, but there's her boyfriend. He's very broad-shouldered.
  #Person2#: He's huge! He must go to the gym to have a well-built body like that.
  #Person1#: Do you prefer tall girls or short ones?
  #Person2#: I don't mind, but I like girls with long hair.
  #Person1#: We have different tastes. I like girls with short hair. I like tall girls-probably because I'm so tall myself.
  #Person2#: Have you ever dated a girl taller than you?
  #Person1#: No, never. I don't think I'Ve ever met a girl taller than me! Have you gained weight recently?
  #Person2#: Yes, I have. Perhaps I should go to the gym, like that girl's boyfriend.
  #Person1#: I'm getting a bit plump myself. Perhaps I'll go with you.
