THE WOLF AND THE SHEPHERD

A wolf followed along after a flock of sheep without doing them any harm. At first the shepherd kept his eye on the wolf as a potential enemy to the flock and never let him out of his sight. But as the wolf continued to accompany the shepherd and did not make any kind of attempt to raid the flock, the shepherd eventually began to regard the wolf more as a guardian of the flock than as a threat. Then, when the shepherd happened to have to go to town, he commended the sheep to the wolf in his absence. The wolf seized his chance and attacked the sheep, slaughtering most of the flock. When the shepherd came back and saw that his flock had been utterly destroyed, he said, 'It serves me right! How could I have ever trusted my sheep to a wolf?'
The same is true of people: if you entrust your bank deposits to greedy men, you are certain to get robbed.
