The Bald Man and the Fly

A little fly pricked a man on his bald head. He swatted at her, but she flew away, so he struck himself. The fly began to laugh and the bald man said to her, "Ha, an evil beast! You demand well your death if I struck myself, and you laugh and mock when I did that. But if I had hit you, you would have died."

Men ought not to laugh or scorn the evil of others.
