I can't do nothing for you either, Billy. You know that. None of us can. You got to understand that as soon as a man goes to help somebody, he leaves himself wide open. He has to be cagey, Billy, you should know that as well as anyone. What could I do? I can't fix your stuttering. I can't wipe the razor-blade scars off your wrists or the cigarette burns off the back of your hands. I can't give you a new mother. And as far as the nurse riding you like this, rubbing your nose in your weakness till what little dignity you got left is gone and you shrink up to nothing from humiliation, I can't do anything about that, either. At Anzio, I saw a buddy of mine tied to a tree fifty yards from me, screaming for water, his face blistered in the sun. They wanted me to try to go out and help him. They'd of cut me in half from the farmhouse over there. (137)
