YOU EASILY NOTICE THAT TRAIT IN ANOTHER BECAUSE YOU HAVE THE SAME CHARACTERISTIC IN YOURSELF AND DISLIKE IT IN YOURSELF.

YOUR SHADOW IS OFTEN IN EFFECT WHEN YOU NOTICE A TRAIT IN SOMEONE ELSE THAT REALLY BOTHERS YOU, SUCH AS ARROGANCE, RUDENESS, ETC. WHAT YOU MAY NOT REALIZE IS THAT YOU EASILY NOTICE THAT TRAIT IN ANOTHER BECAUSE YOU HAVE THE SAME CHARACTERISTIC IN YOURSELF AND DISLIKE IT IN YOURSELF. THIS IS WHAT IS MEANT BY THE PHRASE, "OTHER PEOPLE ARE MY MIRROR."
