A young couple moves into a new neighborhood. The wife criticizes her neighbor's laundry hanging on the line, saying it is not clean and she doesn't know how to wash properly. This goes on for a month until one day the wife notices the laundry is clean and comments on it to her husband. The husband reveals he cleaned their windows that morning, implying that her critical view of her neighbor was due to the dirty windows, not the laundry itself. The document encourages people to examine their own mindset and cleanse their perspective before judging others.
