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 （=10 cents） left．He was hungry, so he decided to beg for a meal at the next house．
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 asked, "How much do I owe you?"
"You don't owe me anything, " she replied．"Mother has taught me never to accept pay for a kindness．" He said, "Thank you a lot．" As Howard Kelly left that house, he not only felt stronger physically, but his faith in human race increased．Just a few moments ago, he was about to give up and quit before this point．
Years later, the young woman became seriously ill．The local doctors were baffled and 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 （会诊）．On hearing the name of the town she came from, he immediately rose and went down in his doctor' s gown through the hospital hall into her room．He recognized her at once．He determined to do his best to save her life．
After a long struggle, the battle was won．Dr．Kelly requested the business office to pass the final bill to him for approval．He looked at it and wrote something on the side．The bill was sent to her room, She was afraid to open it because she was sure that it would take the rest of her life to pay it off．Finally she looked, and the note on the side of the bill caught her attention．
It read: "Paid in full with a glass of milk．"
