Peter was cutting a branch off a tree in his garden. While he was sawing, another man passed in the street. He stopped and said, “ Excuse me, but if you continue to saw that branch like that, you will fall down with it.” He said this because Peter was sitting on the branch and cutting it at a place between himself and the trunk of the tree. Peter said nothing. He thought,” This is some foolish person who has no work to do and goes about telling other people what to do and what not to do.” The man continued on this way.
