    It was a cold winter afternoon before Christmas. My parents and I were sitting on the bench (长椅) at Washington Union Station, waiting for the train. A boy sat near us. His old jacket and dirty hands seemed to show that he was homeless.

“He must be cold and hungry. Maybe I should help him,” I said to myself.

Just at that time, a man walked to him, “Excuse me, I bought two boxed meals for my son and me, but one is enough for us. We hate to waste food. Can you help us?”He handed the boy a boxed meal.

The boy thanked him and opened the box happily. Suddenly he stopped. He ran to an old woman in dirty clothes, “A man brought me this warm meal but I just finished eating. Can you help me?” He placed the box in the old woman's hands.

“Sure, son, but you need to share the sandwich and cake with me. It's too much for me.”

We were all touched. Dad went away and soon returned with two cups of coffee and a salad. He went to the boy and the woman, “Excuse me ...”

I ran into a supermarket and bought something with my money. It was so cold that afternoon but I felt warm inside.
