documents: #Person1#: Hey, Amy. I'm getting together with Sarah and Pool tonight, and a few of our other friends are going to join us. We're going out to eat, and then we'll watch a movie. Why don't you come with us?
  #Person2#: Oh, Stewart. I'd love to, but I have to prepare for a test tomorrow.
  #Person1#: Uh, come on! We're planning on having dinner around 6:30, and then seeing a movie at 7:30. We should be home by 10:30, 11:30 at the latest. Come on!
  #Person2#: Ay... I don't think I should. I haven't been feeling well lately.
  #Person1#: Yeah, because you study too hard. Come on, relax! It's Sarah's birthday, too. We're throwing her a small birthday party after the movie. Come on! Best friends always stick together.
  #Person2#: Oh, OK.
