Most people aren't appreciated enough, and the bravest things we do in our lives are usually known only to ourselves. No one throws ticker tape on the man who chose to be faithful to his wife, on the lawyer who didn't take the drug money, on the daughter who held her tongue again and again. All this anonymous heroism.
