《The Boy Who Cried Wolf》
Once upon a time, there was a boy who lived in a small village. One day, he saw a wolf running through the village and he screamed for help. But no one came to help him because they knew he was just making a false alarm.
The next day, the boy saw the wolf again and he screamed for help once more. But again, no one came to help him. The boy felt very sad and disappointed.
After a few days, the boy saw the wolf again and he really needed help. But no one came to help him because they knew he had been making false alarms before. The boy cried wolf again, but no one believed him.
Finally, the wolf came and attacked the village. But everyone was too scared to run for help because they had never believed the boy when he cried wolf before.
The moral of this story is that if you make false alarms, people will not trust you when you really need help.
