Gandalf: "I think you should leave the ring behind, Bilbo. Is that so hard?"

Bilbo: "Well no… and yes!"

Bilbo: "Now it comes to it, I don't feel like parting with it, its mine, I found it, it came to me!"

Gandalf: "There's no need to get angry."

Bilbo: "Well, if I'm angry, it's your fault!" [caresses the ring] "It's mine! My own, my precious."

Gandalf: "Precious? Its been called that before, but not by you."
