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？”
Hi … saw your story and found this on the internet ….
As is often the case, someone has fictionalized the details of this story and gotten some of it wrong, but it is essentially a true event.
Dr. Howard Kelly was a distinguished physician who, in 1895, founded the Johns Hopkins Division of Gynecologic Oncology at Johns Hopkins University. According to Dr. Kelly’s biographer, Audrey Davis, the doctor was on a walking trip through Northern Pennsylvania one spring day when we stopped by a farm house for a drink of water. A little girl answered his knock at the door and instead of water, brought him a glass of fresh milk. He visited with her briefly, then went his way. Sometime after that, the little girl came to him as a patient and needed surgery. After the surgery, the bill was brought to her room and on it were the words, “Paid in full with one glass of milk.”

But in any case, I think the message is still the same …. be generous with our kindness.
