Years ago, I lived in a building in a large city. The next building was only a few feet away from mine. There was a woman who lived there, whom I had never met, yet I could see her seated by her window each afternoon, sewing or reading.

    After several months had gone by, I began to notice that her window was dirty. Everything was unclear through the dirty window. I would say to myself, “I wonder why that woman doesn't wash her window. It really looks terrible.”

    One bright morning I decided to clean my flat, including washing the window on the inside.Late in the afternoon when I finished the cleaning, I sat down by the window with a cup of coffee for a rest. What a surprise! Across the way, the woman sitting by her window was clearly visible. Her window was clean!

    Then it dawned on me. I had been criticizing her dirty window, but all the time I was watching hers through my own dirty window.That was quite an important lesson for me. How often had I looked at and criticized others through the dirty window of my heart, through my own shortcomings?

    Since then, whenever I wanted to judge someone, I asked myself first, “Am I looking at him through my own dirty window?” I try to clean the window of my own world so that I may see the world about me more clearly.

    A poor boy lived in a small town.He sold goods from door to door to pay for school. One day, he 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. So he wrote something down on the medical bill. The woman read the bill, “You have paid it with a glass of milk.”
