documents: #Person1#: why are you in such a good mood today?
  #Person2#: well, yesterday, I decided to face my fear of heights.
  #Person1#: I didn't know you were scared of heights! Was it really bad?
  #Person2#: let me put it this way. I've never seen a professional sorts game in a stadium because I could never get myself to walk to the top of the stairs to sit down.
  #Person1#: so what did you do about it yesterday?
  #Person2#: I went sky-diving!
  #Person1#: you're kidding me! that sounds really scary!
  #Person2#: It was scary, but it felt great, too.
  #Person1#: weren't you scared?
  #Person2#: of course I was scared. But I had an instructor that went with me and that helped.
  #Person1#: so have you cured your fear of heights?
  #Person2#: I think so. After I jumped out of the plane, I realized that I should just enjoy life. Worrying about it or not doing things out of fear is just plain silly.
  #Person1#: I'm impressed.
  #Person2#: are you scared of anything?
  #Person1#: well, sometimes I get scared when I'm in my apartment all by myself.
  #Person2#: what do you think is going to happen?
  #Person1#: I always worry that the door is unlocked or that a window is open and that a stranger will come in and steal my things.
  #Person2#: it sounds like you just need to be more careful.
