Once upon a time, there was a little girl named Lily. One day, Lily went to visit her friend Tim. Tim lived near the shore. They both loved to play by the water.
As they played, they saw a brilliant shell. "Look, Lily!" said Tim. "What a pretty shell!" Lily smiled and nodded. They both wanted the shell, but they knew they should share.
Lily and Tim decided to take turns holding the shell. They played and laughed all day by the shore. When the sun went down, they gave the shell back to the sea.
The two friends learned that sharing made them happy. They knew that playing together was better than having the shell all to themselves. And so, Lily and Tim stayed best friends forever.
