answer: #Person1# is expressing #Person1#'s dissatisfaction with William and says everyone being friends with him is dumb, which embarrasses #Person1# since #Person1# is William's friend.
documents: #Person1#: Thanks. Sometimes talking with a friend is a great way to get over something. Do you mind if I vent a little bit?
  #Person2#: Of course not. If you're feeling bad and want to let your emotions out, you can just say whatever you want to me.
  #Person1#: Great, because I am really mad at William. I mean, what kind of an idiot wouldn't be able to appreciate a smart, beautiful woman like me? Anybody who would be friends with that guy has to be really dumb.
  #Person2#: Uh, A. . . you know I'm friends with William.
  #Person1#: Oh right. . . present company excluded, of course!
