A dangerous pool

Jimmy lived in the country and he loved to play in a small river near the house. But then his father got a job in a big city, and Jimmy went to live there with his family.

Their new house had a big garden, but the garden was very small. Jimmy wasn't very happy. "Is there a river near there?" he asked his mother on the first morning. His mother answered, "No, there is not, but there's a beautiful park near here, Jimmy, and there's a pool in it. We'll go there this afternoon." Jimmy was happy.

After lunch, Jimmy and his mother went to the park. Jimmy wanted to come near the pool, but there was a warning in front of it. His mother read it to him. "This pool is dangerous. 157 people fell into it." Jimmy looked into the pool and then said, "I can't see them."
