A young couple moves into a new neighborhood. The wife criticizes her neighbor's laundry hanging outside, 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 credits her neighbor with learning how to wash correctly. Her husband reveals he cleaned their windows that morning, implying the wife's critical view of the neighbor was due to the dirty windows, not the laundry itself. The document encourages examining one's own mindset before judging others, as our view depends on the clarity of our own "window."
