documents: #Person1#: Julia, how was your trip to Amsterdam?
  #Person2#: It was great. You know the best thing I did? I rented a bicycle. It was really cool. I got to leave the college area and go out and meet some locals. They were really surprised when they found out I was American.
  #Person1#: Why is that?
  #Person2#: Well, they think Americans are all rich and fat and drive cars and never ride bicycles.
  #Person1#: Yeah, well, that's kind of true.
  #Person2#: Yeah, another interesting thing is that nobody locks their bikes there.
  #Person1#: Really?
  #Person2#: Yeah. I guess you don't have to. Nobody steals them.
  #Person1#: Why not?
  #Person2#: I guess it's because everybody has a bike.
  #Person1#: Hmm...That makes sense.
