Once upon a time, there was a big rock in a small park. A little boy named Tim wanted to play with the rock, but it was too big for him. He tried to push it, but it did not move. Tim felt very tired.
A kind squirrel saw Tim and asked, "Why are you tired, Tim?" Tim said, "I want to play with the big rock, but I can't move it." The squirrel thought for a moment and said, "Let's break the rock into smaller pieces so you can play with them."
So, they both worked together to break the rock. Tim used a small stick, and the squirrel used its little paws. After some time, the rock broke into smaller pieces. Tim was very happy, and he played with the small rocks all day. The squirrel and Tim became good friends, and they played in the park every day.
