Well, when you're fourteen years old, you can't afford to mix in a rock fight with your five-year-old brother. You can't do it, even when you're in the right. You just can't explain a thing like that to your folks. All they'll do is point out how much bigger you are, how unfair it is to your little brother.
That was as rough a thing as I ever heard tell of happening to a boy. And I'm mighty proud to learn how my boy stood up to it. You couldn't ask any more of a grown man... It's not a thing you can forget. I don't guess it's a thing you ought to forget. What I mean is, things like that happen. They may seem mighty cruel and unfair, but that's how life is part of the time. But that isn't the only way life is. A part of the time, it's mighty good. And a man can't afford to waste all the good part, worrying about the bad parts. That makes it all bad.
