On Monday morning, I was on my way to school when suddenly as I saw a boy knocked down
by the car. In a hurry, I ran over and found the boy was serious hurt with much blood on his face.
Immediately, I call an ambulance and the boy was taken to the nearest hospital. For my relief, the
boy was fine and would recover in a few day. I went away without leaving his name. I was late for
class, and I felt happy for what I had done. As a proverb says, “Help others is the source of happiness.”
I feel our duty to make the world a better place to live in.
