A retired boss recounted that when he was a young boy, his mafioso father made him climb a wall and then invited him to jump, promising to catch him. He at first refused, but his father insisted until finally he jumped—and promptly landed flat on his face. The wisdom his father sought to convey was summed up by these words: "You must learn to distrust even your parents."
