Once upon a time, there was a little girl named Lucy. She loved to eat dessert. Her favorite dessert was a big, yummy cake. One day, Lucy found a cake on the table. It was wrapped in a pretty, shiny paper. Lucy was very happy and excited to eat the cake.
But Lucy had been playing outside all day, and her hands were filthy. Her mom told her, "Lucy, you have to wash your hands before you eat the cake." Lucy didn't want to wait, but she knew her mom was right. So she went to the sink and washed her hands with soap and water.
When Lucy's hands were clean, she went back to the table. She carefully unwrapped the cake and shared it with her family. They all enjoyed the dessert together. Lucy was so happy she had listened to her mom and washed her hands. The cake was so tasty, and it was even better because she was clean.
