documents: #Person1#: Johnny, are you just sitting around again?
  #Person2#: I'm just taking a break between washing the windows and cleaning the toilet.
  #Person1#: I'd say all you've done is moved the dirt from the windows on to your face and hands. Disgraceful!
  #Person2#: I'm doing my best, Grandma. . .

  #Person2#: Uh-oh, here we go. . .
