A man was leading his donkey down a road, when the donkey got free and ran to the edge of high cliff. The man ran as fast as he could to the donkey and grabbed his tail to stop the donkey from going off the edge of the cliff. But the donkey was stubborn; the more the man tried to stop him, the more the donkey pulled the other way.

     "Oh well," said the man, "if you are determined to go your own way, I cannot stop you."
