A Quote from Fallout 3
Moira Brown, Player
Moira: It's like... Did you ever try to put a broken piece of glass together? Even if the peices fit, you can't make it whole again the way it was. But if you're clever, you can still use the pieces to make other useful things. Mabye something wonderful, like a mosaic. Well, the world broke like glass, and everyone's trying to put it back together like it was, but it'll never come together the same way.
Player: I don't know. Human nature doesn't change like that.
Moira: Maybe, I've certainly heard people say that. But isn't it also human nature to try to do better than we always have?
