Once upon a time, in a small house, there lived a girl named Lily. She loved to create things with her toys. One day, she decided to make a big mattress for her dolls. She used soft pillows and a soft blanket. She was very happy with her creation.
Lily's brother, Tom, saw the mattress and said, "That's a stupid idea! Dolls don't need a mattress." Lily felt sad, but she knew her dolls would love it.
"Tom, don't be mean!" said Lily. "My dolls will sleep better on this mattress." Tom rolled his eyes, but he left her alone. Lily put her dolls on the mattress and told them a bedtime story. They all slept very well that night. In the end, Lily knew that her creation was not stupid at all.
