Helping Others Is Happy
I am a Chinese student in a city. In my past, I always spent much money on buying clothes and snacks. However, I am different now. It was three years ago that my teacher told us there are a lot of poor children who have no clothes or food, and they cannot afford to school. Since then, I have been donating almost all of my pocket money to an organization called UNICEF, which helps children to get education. I am so proud of myself that I can help others by this way. We will always feel happy when we are helping others.
