Once upon a time, there was a nice girl named Lily. She loved to play with her friends outside. They liked to run, jump, and laugh in the fresh air. The air was full of oxygen, which helped them breathe and have fun.
One day, Lily and her friends found a big log. They thought it would be fun to walk on it. They took turns trying to balance on the log. Some of them wobbled and almost fell, but they all tried their best.
In the end, Lily was the best at balancing on the log. Her friends clapped and cheered for her. They all had a nice day playing outside, breathing the oxygen, and learning to balance. And they all lived happily ever after.
