documents: #Person1#: God, I didn't realize. I didn't, I didn't know. . .
  #Person2#: . . . Who you were with? I didn't know whom you were with.
  #Person1#: Excuse me?
  #Person2#: Sorry, it's from the Godfather. It's when the, when the movie producer realizes Tom Higgins had emissary of Vito Corleone, it's just before the horse's head ends up in the bed with all the bloody sheets, you know, wakes up, and AAAL! Never mind.
  #Person1#: You were spying on me, weren't you? You probably rented those children.
  #Person2#: Why would I spy on you?
  #Person1#: Because I am your competition which you know perfectly well, or you would not put up that sign just around the corner.
  #Person2#: The entrance to our store is around the corner. And there's no other way of saying that. It's not the name of our store. It's where it is. And you do not own the phrase around the corner.
  #Person1#: What is that? What are you doing? You're taking all the caviar! That caviar is a garnish?
  #Person2#: Look, the reason I came into your store is because I was spending the day with Annabell and matt. And I was buying them presents. I'm the type of guy who likes to buy his way into the hearts of children who are his relative. And there's only one place to find a children's book in the neighborhood. That will not always be the case. And it was yours. And it is a charming little bookstore. You probably sell what 350, 000 worth of books in a year.
