One day, a poor boy who was trying to pay his way through school by selling goods door to door found that he only had one dime left. He was hungry so he decided to beg for a meal at the next house.

一天，一个贫穷的小男孩为了攒够学费正挨家挨户地推销商品。饥寒交迫的他摸遍全身，却只有一角钱。于是他决定向下一户人家讨口饭吃。

However, he lost his nerve when a lovely young woman opened the door. Instead of a meal he asked for a drink of water. She thought he looked hungry so she brought him a large glass of milk. He drank it slowly, and then asked, “How much do I owe you?”

然而，当一位美丽的年轻女子打开房门的时候，这个小男孩却有点不知所措了。他没有要饭，只乞求给他一口水喝。这位女子看到他饥饿的样子，就倒了一大杯牛奶给他。男孩慢慢地喝完牛奶，问道：“我应该付多少钱?”

“You don't owe me anything,” she replied. “Mother has taught me never to accept pay for a kindness.” He said, “Then I thank you from the bottom of my heart.” As Howard Kelly left that house, he not only felt stronger physically, but it also increased his faith in God and the human race. He was about to give up and quit before this point.

年轻女子微笑着回答：“一分钱也不用付。我妈妈教导我，施以爱心，不图回报。”男孩说：“那么，就请接受我由衷的感谢吧!”说完，霍华德-凯利就离开了这户人家。此时的他不仅自己浑身是劲儿，而且更加相信上帝和整个人类。本来，他都打算放弃了。

Years later the young woman became critically ill. The local doctors were baffled. They finally sent her to the big city, where specialists can be called in to study her rare disease. Dr. Howard Kelly, now famous was called in for the consultation. When he heard the name of the town she came from, a strange light filled his eyes. Immediately, he rose and went down through the hospital hall into her room.

数年之后，那位女子得了一种罕见的重病，当地医生对此束手无策。最后，她被转到大城市医治，由专家会诊治疗。大名鼎鼎的霍华德-凯利医生也参加了医疗方案的制定。当他听到病人来自的那个城镇的名字时，一个奇怪的念头霎时间闪过他的脑际。他马上起身直奔她的病房。

Dressed in his doctor's gown he went in to see her. He recognized her at once. He went back to the consultation room and determined to do his best to save her life. From that day on, he gave special attention to her case.

身穿手术服的凯利医生来到病房，一眼就认出了恩人。回到会诊室后，他决心一定要竭尽所能来治好她的病。从那天起，他就特别关照这个对自己有恩的病人。
