Once upon a time, there was a mechanic named Tom. Tom loved to build things. He had a big workshop with lots of tools. Tom was very good at fixing things, but sometimes he did stupid things.
One day, Tom wanted to build a big tower. He started to put blocks on top of each other. The tower got taller and taller. Tom's friend, Sam, came to visit and saw the tall tower.
Sam said, "Wow, Tom! That's a big tower! But be careful, it might fall!"
Tom laughed and said, "I'm not stupid, Sam. I can build a very tall tower, and it won't fall!"
But just as Tom put the last block on top, the tower started to shake. The blocks fell down and made a big mess. Tom and Sam laughed together. Tom learned that it's okay to make mistakes, even if they are stupid.
