Once upon a time, there was a little boy named Timmy. Timmy loved to play tricks on his friends. One day, he decided to play a trick on his best friend, Sam.

Timmy told Sam that there was a magical tree in the park that could grant wishes. Sam was very excited and asked Timmy how he knew about this magical tree. Timmy replied, "I just found it yesterday while I was playing hide and seek."

Sam was eager to try out the magic of the tree. He ran to the park with Timmy and stood under the tree. Timmy told him to close his eyes and make a wish. Sam closed his eyes tightly and wished for a new bicycle.

When Sam opened his eyes, he didn't see a bicycle anywhere. He looked at Timmy, puzzled. Timmy burst out laughing and said, "I guess the tree needs batteries!"

Sam laughed too, realizing he had been tricked. From that day on, they both agreed never to believe everything Timmy said without checking first.

This simple story teaches us the importance of critical thinking and not jumping to conclusions. It also reminds us to have fun and enjoy life's little jokes with our friends.
