Two pockets 1

Prometheus created man, and hung two bags around each person's neck - one for the faults of others, and the other for one’s own faults. He hung the bag of others’ faults in front of them, and the bag of their own faults behind them. Therefore, people are always able to see the faults of others quickly, while they cannot see their own.

This story illustrates that people tend to like pointing out others' faults while ignoring their own.
