My brother-in-law is a simple man. He’s not stupid, but he’s no genius. He doesn’t have a powerful, important job; he’s a truck driver. He doesn’t drive a fancy car; he drives a pickup truck. And he’s the only person I’ve ever met who could say, without any hint of embarrassment or self-consciousness, “I don’t understand.”

Rarely do misunderstandings occur with him, because when he doesn’t understand something that is said to him or asked of him, he just says, “I don’t understand.” And he keeps saying it until he does understand.
