The story is about a young woman who criticizes her neighbor for having dirty laundry hanging outside to dry. Every time she sees the neighbor's laundry, the woman makes negative comments. One day, the woman is surprised to see the neighbor has learned to wash correctly with clean laundry on the line. Her husband reveals he cleaned their windows that morning, implying that the woman was making unfair judgments due to the impurities in her own perspective. The story suggests that how we see others depends on our own state of mind, and we should check our motives before criticizing or judging others.
