It was a cold winter afternoon before Christmas My parents and I were sitting on the bench 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,
