A poor boy lived in a small town. He sold goods from door to door to pay for school. One day, he had only one cent left, and he was hungry. He decided that he would ask for a meal at the next house. However, when a young woman opened the door, the boy was shy, so he just asked for some water. The woman knew he was hungry, so she brought him a large glass of milk. He drank

it slowly, and then asked, “How much should I pay for it？” “You won't pay for it. My mother has

told me that it is good to help the people who are in trouble，” she replied. The boy said, “Then I thank you from my heart.” As the boy left that house, he felt stronger. He knew he had many things to do.

Many years later, the young woman became ill. The local doctors couldn't save her. People had to send her to a big city. When the doctor knew who the woman was, he was excited and tried his best to save her life. He succeeded. The woman needed to pay for the medical bill. The doctor learned that she couldn't afford it.
