Gandalf: The world is not in your books and maps. It’s out there.
Bilbo Baggins: I can’t just go running off into the blue! I am a Baggins of Bag End!
Gandalf: You are also a Took. Did you know that your Great-Great-Great-Great Uncle Bullroarer Took was so large he could ride a real horse?
Bilbo Baggins: Yes.
Gandalf: Well he could! In the Battle of Greenfields, he charged the Goblin ranks. He swung his club so hard it knocked the Goblin King’s head cleaned off and it sailed a hundred yards through the air and went down a rabbit hole. And thus the battle was won and the game of golf invented at the same time.
Bilbo Baggins: I do believe you made that up.
Gandalf: Well, all good stories deserve embellishment. You’ll have a tale or two to tell of your own when you come back.
Bilbo Baggins: …Can you promise that I will come back?
Gandalf: No. And if you do… you will not be the same.
