Why do you think Bandini reacts the way he does to Judy?

Judy is only person in the hotel who has read, The Little Dog Laughed, which she thinks is a wonderful story, and the reason she goes to visit Arturo, hoping he will give her a copy of the magazine. Arturo is so excited to have a fan who has read his story that he invites her in, gets her a chair, and offers her water or an ice cream, or Coke or root beer.
