Once upon a time, there was a happy little girl named Mia. She loved to play on the beach and find pretty shells. One sunny day, she went to the beach with her mom and dad.
At the beach, Mia found lots of shells. She was very excited. She wanted to sort the shells by their size and color. She put big shells in one pile and small shells in another pile. Mia's mom and dad watched her and smiled.
But then, a big wave came and washed away all the shells that Mia had sorted. Mia was very sad. Her mom and dad tried to make her feel better, but the shells were gone. They went back home, and Mia did not have her pretty shells anymore.
