Red: I played a mean harmonica as a younger man. Lost interest in it though. Didn't make much sense in here.
Andy Dufresne: Here's where it makes the most sense. You need it so you don't forget.
Andy Dufresne: Forget that... there are places in this world that aren't made out of stone, and that there's something inside that they can't get to, and that they can't touch. It's yours.
Red: What're you talking about?
Andy Dufresne: Hope. Hope is a good thing. Maybe the best of things. And a good thing never dies.
