[Q]: 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 .
