[Sam] I know: It’s all wrong. By rights we shouldn’t even be here. But we are. It’s like in the great stories, Mr. Frodo. The ones that really mattered. Full of darkness and danger they were. And sometimes you didn’t want to know the end. Because how could the end be happy? How could the world go back to the way it was when so much bad had happened? ….. But in the end, it’s only a passing thing, this shadow. Even darkness must pass. A new day will come. And when the sun shines it will shine out the clearer. Those were the stories that stayed with you. That meant something, when you were too small to understand exactly why…. But now I think, Mr. Frodo, I do understand. I know now. Folk in those stories had lots of chances of turning back, only they didn’t. They kept going, because they were holding on to something.
[Frodo:] What are we holding on to, Sam?
[Sam:] That theres some good in this world, Mr Frodo. And that it’s worth fighting for.– Lord of the Rings, “The Two Towers”
