The Wolf and the Crane

A Wolf had been gorging on an animal he had killed, when suddenly a small bone in the meat stuck in his throat and he could not swallow it. He soon felt terrible pain in his throat and ran up and down groaning and seeking for something to relieve the pain. He tried to induce everyone he met to remove the bone. "I would give anything," said he, "if you would take it out." At last the Crane agreed to try and told the Wolf to lie on his side and open his jaws as wide as he could. Then the Crane put its long neck down the Wolf's throat, and with its beak loosened the bone, till at last it got it out.

"Will you kindly give me the reward you promised?" said the
Crane.

The Wolf grinned and showed his teeth and said: "Be content. You have put your head inside a Wolf's mouth and taken it out again in safety; that ought to be reward enough for you."

And, the moral is…

Gratitude and greed do not go together.
