Once upon a time, there was a little boy named Tim. Tim loved to play with his toys. One day, he found a big, heavy rock in the yard. He thought it would be fun to play with it.
Tim tried to squeeze the rock in his hands, but it was too heavy. He asked his mom for help. She told him that it was not a good idea to play with heavy things. Tim didn't listen and kept trying to play with the rock.
Later, Tim's toy car broke. He was very sad. His mom told him that they needed an operation to fix it. Tim learned that playing with heavy things can break other things. The moral of the story is to listen to your mom and be careful with heavy things.
