One night a man came to our house and told me, “There is a family with eight children. They have nothing to eat for days.”

I took some food and went. When I finally came to the family, I saw the ugly face of those little children by hunger. There was no sorrow (悲伤) or sadness in their faces, just the deep pain of hunger.

I gave the rice to the mother. She divided(分) it into two, and went out, carry half the rice with her. When she came back, I asked her, “Where did you go?” She gave me this simple answer, “To my neighbours----they are also hungry.”

I was not surprised that she gave----because poor people are unselfish(无私的). But I was surprised that she knew they were hungry. As a rule, when we are in trouble, we think more about ourselves, and have no time for others.
