A person with humility does not feel angry if he is interrupted in the middle of doing something. He always sees the virtues of the person who interrupted him, and considers that person important.

If a king interrupted a woodchopper in the middle of chopping wood, the woodchopper would not be offended -- since he is aware of how distinguished the king is. Similarly, the humble person always appreciates the greatness in each person and is not offended if they interrupt him.
