     The cold wind cut through my enthusiasm (热情) as a tourist in Washington D.C., so I entered the

nearest restaurant for warmth. I ordered a coffee, and began observing people.

     At that time, I saw a man seated nearby and from his eager eyes, I realized that he noticed the

delicious food. His tired body and worn clothes shouted, "Homeless, homeless!"

     "How long has it been since he ate last time?" I wondered. I expected him to approach me for a

handout (施舍物). But he never did. A silent war broke out in my head-one side was telling me to mind

my own business, and the other was urging me to offer him some food.

     While my inner debate moved on, a well-dressed young couple walked up to him. "Excuse me, sir,

"the husband began. "We just finished eating, and our appetites (胃口) weren't as big as we had thought. We hate to waste good food. Can you help us out and put this to use?" He gave the man some food.

"Thank you. Merry Christmas!" the man replied. The man carefully watched his new food, and was about

to eat.

     Something that happened next shocked me. An old man in pants, an old jacket and open shoes

entered the hall and walked towards us. My neighbor saw the situation. Setting aside his meal, he stood

up and guided the old man to the table.

     "Hi, my name is Jack," he said, "and one kind person brought me this meal. I just finished eating and

hate to waste good food. Can you help me out?" The old man answered gratefully, "Sure, but only if you

go halfway with me on that sandwich."

     I left the restaurant that day feeling warmer than I had ever thought possible.
