The Dog and His Image

A Dog, with a bit of meat in his mouth, was crossing a river. Looking down he saw his image in the water, and thought it was another dog, with a bigger piece. So he dropped what he had, and jumped into the water after the other piece. Thus he lost both pieces: the one he really had, which he dropped; and the other he wanted, which was no piece at all.

This is a good fable for greedy people.
