Don't Judge a Book by Its Cover

Lily is talking to her singer friend, Chad.
L: Chad, what a lucky guy you are!
C: What do you mean?
L: Well, you've got everything a person could ask for: a lovely family, money and fame.
C: Nothing's as wonderful as it seems.
L: But such a successful man as you must surely be happy.
C: Not really, I'm so busy that I don't live a normal life.
L: Anyway, I wouldn't mind being in your shoes.
C: And I would love to be able to live as simple a life as you do.
L: I guess you should never judge a book by its cover.
C: How right you are!
