documents: #Person1#: Jim? Jim? ... What are you doing in the kitchen?
  #Person2#: Nothing, Mummy. I was hungry so I came here for some milk.
  #Person1#: Milk? I thought you didn't like milk.
  #Person2#: I don't, but I couldn't find anything to eat in the refrigerator.
  #Person1#: Nonsense. There's lots of food in the refrigerator... What's behind your back?
  #Person2#: Nothing.
  #Person1#: What are you hiding behind your back? Let me see.
  #Person2#: Promise that you won't get angry.
  #Person1#: OK, I promise. What is it?
  #Person2#: It's a kitty.
  #Person1#: Oh, Jim. I told you. No pets. It'll make a mess of this house.
  #Person2#: Please, Mummy. Everybody else in my class keeps a pet. Please, I'll take care of it. It's a good kitty. It'll not bring you any trouble.
  #Person1#: No way. It might belong to somebody else. You can't keep it here.
  #Person2#: Please, Mummy. I found it this afternoon by the garbage bin. It was starving and looking for something to eat. Please! You see, it's so cute and tame.
  #Person1#: All right. But you have to clean up everything it messes up.
  #Person2#: I will. Thank you, Mummy.
