Long ago, there was a young, cheeky boy who looked after some sheep near a village. The boy who often bored. 

One day, he played a trick on the villagers to pass the time.

"Wolf! Wolf!" he shouted loudly.

The villagers came running up the hill to save the sheep. However, when they got there, there was no wolf. The boy laughed at them. "I tricked you!" he said.

"You must not tell lies!" said the villagers angrily and went back to the village.

Soon, the boy was bored again. He thought for a minute and shouted, "Wolf! Wolf!" Again, the villagers rushed up the hill to save the sheep.

The boy laughed at them. "I tricked you again!" he said.

"You must not tell lies!" shouted the villagers. They hurried back down to the village.
