On the morning of last Friday, Peter went to school as usual. He was walking along the road when he saw a well uncovered. He thought it was dangerous for passers-by, so he decided to cover the well. The cover was so heavy that he took great trouble to remove it. At last he managed to cover the well. Hardly had he turned his back and gone when he heard a cry for “Help” coming from the well. So he turned back and moved the cover away. To his surprise, a worker was inside the well. Peter tried his best to pull the worker out of the well. After that Peter covered the well again properly.
