The Boy Who Cried Wolf (A Modern Retelling)

Once upon a time, there was a young man named Peter, who worked as a security guard at a museum. He was bored on the job, so one day he started to prank people. He hid in the shadows and yelled, "We're being robbed!", causing people to run and scream. People were scared and came running to help. Again on the next day, Peter yelled, "We're being robbed!". All the people in the museum came running to help, but they were disappointed to find that they had been tricked once again.

One day, there was a real intruder at the museum. Peter saw the thief, and he yelled for help at the top of his lungs. But by this time, everyone thought it was just another false alarm. Peter was too afraid to confront the thief alone so he hid in the broom closet. As a result, the thief was able to steal valuable paintings and artifacts.

Moral of the story:

If you always lie, people will eventually stop believing what you say. Even when you're telling the truth, no one will believe you.
