A SHEPHERD driving his Sheep to a wood, saw an oak of unusual
size full of acorns, and spreading his cloak under the branches,
he climbed up into the tree and shook them down.  The Sheep
eating the acorns inadvertently frayed and tore the cloak.  When
the Shepherd came down and saw what was done, he said, "O you
most ungrateful creatures! You provide wool to make garments for
all other men, but you destroy the clothes of him who feeds you."
