This has happened to you.
You’re standing in a crowded room. Someone pushes into you from behind. You feel a surge of irritation, even anger. Who is this careless oaf who can’t respect your personal space? You turn around to express your indignation, only to discover that the offending party is actually a good friend of yours who has bumped into you accidentally or, perhaps, even on purpose and is not smiling at you as you find yourself on the receiving end of a good-natured prank.
Your anger evaporates in an instant.
But why? The bump was no less of a bump on account of the person who bumped you. But the bump was never the issue at all. What was at issue was your ego, resenting the perpetrator who failed to show you respect.
It’s almost always ego that is the real perpetrator in any fight. Change one little detail and our irritation or anger vanishes. But when we feel our ego has been affronted, heaven help the offending party.
A folktale
A man woke up one Sunday morning convinced that it was Monday. No one could tell him otherwise, and all the evidence his family and coworkers rallied made no impression upon him whatsoever. On Monday he asserted it was Tuesday, and on Wednesday he insisted it was Thursday. He refused to entertain the notion that he might be wrong and that everyone else might be right.
