Lily and Tom were playing in the park with their toys. They liked to make sand castles and dig holes. They had a bucket, a shovel, and some cars.
"Look, Lily, I made a big castle!" Tom said, showing his sand creation.
"It's very nice, Tom. But I think you need a moat to protect it from enemies," Lily said, recommending a way to improve his castle.
"A moat? What's that?" Tom asked.
"It's a water ring around the castle. Like this," Lily said, digging a ditch around her own castle and filling it with water from the bucket.
"Oh, I see. That's cool. Can you help me make one?" Tom said.
"Sure, Tom. Here, take the shovel and dig here," Lily said, pointing to a spot near his castle.
They worked together to make a moat for Tom's castle. They were having fun and did not notice the dark clouds in the sky. Soon, it started to rain. The rain was fierce and heavy. It made the sand wet and sticky. It also made the water in the moats rise and overflow.
"Uh-oh, Lily, look! The water is coming out of the moats. It's a flood!" Tom said, worried.
"Oh no, Tom, you're right. The flood is ruining our castles. We have to save our toys!" Lily said, grabbing her cars and putting them in the bucket.
"Quick, Lily, let's go to the slide. It's high and dry there. We can wait for the rain to stop," Tom said, following her with his bucket.
They ran to the slide and climbed up. They put their buckets on the platform and looked at the park. The park was full of water and mud. Their castles were gone. They felt sad.
"I'm sorry, Tom. I didn't mean to make a flood," Lily said.
"It's okay, Lily. It's not your fault. The rain did it. Maybe we can make new castles when the sun comes out," Tom said.
"I hope so, Tom. I like playing with you. You're a good friend," Lily said.
"Me too, Lily. You're a good friend too. And you have good ideas. I like your moat recommendation," Tom said.
They smiled and hugged. They waited for the rain to stop and the flood to go away. They hoped to play in the park again soon.
