documents: #Person1#: I know I'm a blabbermouth, but what do you think she should do, John? 
  #Person2#: Honey, we're in the museum now. We're not here to discuss your coworker's love life. We're here to enjoy the great paintings by Picasso! 
  #Person1#: I know! But it's really important to her! Her whole life could be ruined by this man! 
  #Person2#: You're making a federal case out of it. One unhealthy love affair can't ruin anything. It could even make your life more interesting. 
  #Person1#: Are you serious, John? 
  #Person2#: All I'm trying to say is that life is. . . like. . . er . . . this painting.
