Many years ago, I lived in a building in a large city. The building next door 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.
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 morning I cleaned my room, 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 seen. Her window was clean!
