Being right later doesn’t erase how you acted when you thought you were losing.

Vindication clears up the facts and leaves the conduct exactly where it was. People remember the shouting, the sarcasm, the thing you said when it looked like it was going badly, and being correct in the end does not reach back and tidy any of that. You get the point and keep the behaviour.

Watch yourself in the middle of the next disagreement, when you have no idea how it will end. That is the part worth governing. Aim to be someone who would not need to apologise for how they were, whichever way the facts fall.
