Quote from : The Lord of the Rings: The Return of the King Movie

Frodo: [voiceover] And thus it was. A fourth age of middle-earth began. And the fellowship of the ring... though eternally bound by friendship and love... was ended. Thirteen months to the day since Gandalf sent us on our long journey... we found ourselves looking upon a familiar sight. We were home. How do you pick up the threads of an old life? How do you go on... when in your heart you begin to understand... there is no going back? There are some things that time cannot mend... some hurts that go too deep... that have taken hold. Bilbo once told me his part in this tale would end... that each of us must come and go in the telling. Bilbo's story was now over. There would be no more journeys for him... save one. My dear Sam. You cannot always be torn in two. You will have to be one and whole for many years. You have so much to enjoy and to be and to do. Your part in the story will go on.
