The Shepherd’s Boy and the Wolf (The Boy Who Cried Wolf)
A young Shepherd, bored while watching sheep, shouted, “Wolf! Wolf!” as a prank.
Villagers ran to help, but there was no wolf. He laughed.
He repeated the trick a few times. But when a real Wolf came, no one believed him—and the Wolf killed many sheep.
Moral: Liars are not believed, even when they tell the truth.
