  #Person2#: Why not? It's my parking space.
  #Person1#: I'm afraid not, sir.
  #Person2#: Oh? That's a surprise. Let me see... D 0411 Our dog's birthday. Yes, I'm sure this my parking space!
  #Person1#: But I saw a red car always parking here before.
  #Person2#: Oh, we've just repainted our car. It was red.
