documents: #Person1#: Mrs. Montgomery? I'Ve been trying to figure out when we should have the New Year's party. Could you take a book at these dates?
  #Person2#: Sure. The twenty-ninth is out. I'll be out of the office all day at a seminar. Either the twenty-eighth or the thirtieth is fine.
  #Person1#: Well, why don't we make it the thirtieth? We can set it up from three to five. That way, everybody can just go home afterwards.
  #Person2#: Sounds good to me. You make up the invitations, I'Ve got run. I'Ve got a meeting in five minutes.
