One day, a little girl named Lily went to the kitchen. She wanted to wash her hands in the sink. But when she tried, she found that the water was too hot. "Ouch!" she said. "The water is hot! I need gentle water to wash my hands."
Lily's big brother, Tom, heard her. He came to help her. "I can make the water gentle for you," he said. Tom turned the other tap, and the water became gentle. But then, the sink started to fill up too much. The water was going to spill out of the sink!
"Oh no!" said Lily. "The sink is too full! What do we do?" Tom thought for a moment. "We need to turn off the water," he said. They both reached for the taps and turned them off together. The water stopped, and the sink was safe.
Lily and Tom smiled at each other. They had worked together to fix the problem. Now, they could both wash their hands with the gentle water in the sink.
