Don’t end the argument with a winner. End it with a next step.

Arguments that end with a scoreboard leave the actual problem exactly where it was. Someone walks away proven right, and the thing you were fighting about is still sitting there on Monday. What closes a disagreement is not a verdict but an agreement about what happens next.

Notice the moment a conversation turns into evidence gathering instead of problem solving. Ask what the two of you will do differently tomorrow, and keep the answer small enough to actually happen.
