There was a Shepherd who was once taking his Sheep to a wood, while going he 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 also ate the cloak and tore it.
When the Shepherd came down and saw what was done, he said, "O you most ungrateful creatures! I am the one to whom you provide wool to make garments for all other men, but you destroy the clothes of him who feeds you."
