题目内容：

I was sitting in a fast food restaurant with my two children, who at the time were about 6 and 9. Inside there was also a group of teens in Gothic(哥特式的) dress and appearance. Everyone kept away from them inside the restaurant.

Outside the restaurant, people jumped past the homeless man searching the garbage bin, who was looking for food or perhaps a cigarette. I too had rushed past him with my youngsters, refusing his request for money but thinking maybe, just maybe, I would bring him some food. It turned out that I didn't have to.

One girl in the Gothic youth jumped up, went to the counter and ordered more food, which she then took outside to the homeless man and sat on the bench with him, chatting away as he ate. He didn't say much—he was greedy—but I think I saw a bit of a smile and a flash in his eyes as he nodded to her questions.

Writing this now, several years later, I still choke up. That girl was a model citizen living the values of goodness and kindness. These are values I have always held high and hoped to teach my kids. She made my job much easier. We stopped by on our way out and thanked her for setting such a positive example for us. I hope that hearing that has made as much of a difference in her life as seeing what she did has made to ours.
