If I tear open that chest of yours, will I see it there? If I smash open that skull of yours, will I see it there?”

“You can close your eyes to the things you do not want to see, but you cannot close your heart to the things you do not want to feel.”

“To see certain things, you have to be lying on your back with tears in your eyes and a scalding potato in your mouth. It's possible, I think, that you have to be hurt to see anything at all.”
