A Wolf once walked behind a flock of Sheep, and did them no harm. At first, the Shepherd treated him as an enemy, and kept watch against him. But when the Wolf made no sign of hurting the Sheep, the Shepherd began to think he was quite as good as a watch-dog.
So one day, when the Shepherd wished to go to the city, he left the Sheep in the care of this quiet Wolf. That was the chance the Wolf wanted, and he made sad havoc with the flock. When the Shepherd came back and saw the Sheep scattered, he said:—
"It serves me right; for why did I trust Sheep to a Wolf?"
