"The Boy Who Cried Wolf" is a popular fable that has been told for centuries. It is about a young shepherd boy who becomes bored while watching over his sheep and decides to play a trick on the villagers by pretending that a wolf is attacking the sheep. The villagers come running to help, only to realize that the boy was lying and there was no wolf.

The boy finds this hilarious and repeats the prank multiple times, each time causing the villagers to rush to his aid only to find that there is no danger. Eventually, a real wolf does appear and the boy cries out for help, but this time the villagers do not believe him and no one comes to his aid. As a result, the wolf attacks the sheep and the boy learns a valuable lesson about the consequences of lying.

This fable is often used to teach children about the importance of honesty and the consequences of deceit. It emphasizes the idea that if you constantly lie or exaggerate the truth, people will not believe you even when you are telling the truth.
