Gandalf: I think you should leave the ring behind, Bilbo. Is that so hard?
Bilbo: Well, no....and yes. Now it comes to it, I don't feel like parting with it. It's 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. ...it's mine... my own... my precious...
Gandalf: Precious? It's been called that before, but not by you.
Bilbo: Oh, what business is it of yours what I do with my own things?
Gandalf: I think you've had that ring quite long enough.
Bilbo: You want it for yourself!
Gandalf: Bilbo Baggins! Do not take me for some conjuror of cheap tricks! I am not trying to rob you. I'm trying to help you.
Bilbo is having trouble leaving the Ring in the Shire as he packs to leave.
