Once upon a time, there was a very naughty shepherd boy. He would take his sheep for grazing, then climb up a tree, and shout for help, claiming that a wolf was attacking his sheep.
Every time this happened, the farmers and other men would come to rescue him and his flock. But once they saw he was lying, they would leave angrily. Then, the boy would laugh. This went on for a long time, but one day, a wolf really came and attacked his sheep. But this time nobody heard him or offered to help him because they did not believe him anymore.
