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 correctly. One month later, the wife sees the neighbor has hung clean laundry and wonders who taught her. The husband reveals he cleaned their windows that morning. The moral is that what we see in others depends on the purity of our own perspective, and we should check our state of mind before criticizing others.
