J.R.R. Tolkien

"As all things come to an end, even this story, a day came at last when they were in sight of the country where Bilbo had been born and bred, where the shapes of the land and of the trees were as well known to him as his hands and toes. Coming to a rise he could see his own Hill in the distance, and he stopped suddenly and said:

Roads go ever ever on,
Over rock and under tree,
By caves where never sun has shone,
By streams that never find the sea;
Over snow by winter sown,
And through the merry flowers of June,
Over grass and over stone,
And under mountains in the moon.

Roads go ever ever on
Under cloud and under star,
Yet feet that wandering have gone
Turn at last to home afar.
Eyes that fire and sword have seen
And horror in the halls of stone
Look at last on meadows green
And trees and hills they long have known.

Gandalf looked at him, "My dear Bilbo!" he said. "Something is the matter with you! You are not the hobbit that you were.""
