The quote is from "A Girl I Knew," a short story by J.D. The story is pretty typical Salinger -- ambiguous and sad and philosophical -- and it's one of my favorites. Salinger had a beautiful way with simple words.
Wicked quote: "As someone told me lately: Everyone deserves the chance to fly. And if I'm flying solo, At least I'm flying free." Do read the book, Wicked, before seeing the play. It's usually good advice for any book made into a movie.
