Insecure people need to win every conversation. Secure people can lose one and still sleep fine.

The compulsion to win small exchanges is a tell. If every disagreement has to end with you on top, your sense of yourself is being settled in public, one argument at a time, which is an exhausting way to live. Somebody steady can concede a point because the concession costs them nothing.

Lose one on purpose this week, something trivial you could have won. Say they are right and leave it there, with no clause attached. Notice that nothing happens, which is the whole lesson, and notice who in your life cannot manage it.
