The Swollen Fox
A very hungry Fox, seeing some bread and meat left by shepherds, crept into the hole and ate the food. When he finished, he was so full that he was not able to get out, and began to groan and cry about his fate. Another Fox passing by heard his cries, and inquired of his complaining. On learning what had happened, he said to him, "Ah, you will have to remain there, my friend, until you become such as you were when you crept in, and then you will easily get out."
What's the lesson?
