" You have these lines you won’t cross. But then you cross them. And suddenly you possess the very dangerous information that you can break the rule and the world won’t instantly come to an end. You’ve taken a big, black, bold line and you’ve made it a little bit gray. And now every time you cross it again, it just gets grayer and grayer until one day you look around and you think, There was a line here once, I think. "
