Some arguments don’t have a finish line. Shake on it, change the subject and go get food.
STILLNESS
STILLNESS
Some disagreements are not problems to solve, they are two people built differently, and no amount of talking will file down the difference. Continuing past that point is not persuasion anymore; it is each of you waiting for the other to become someone else. The relationship pays for the extra hour, not the argument.
Notice when you have started repeating your own points in new words. That is the signal to stop, agree that you see it differently, and go do something ordinary together. Nothing is lost by leaving a question open.
Which disagreement could you drop today without anyone actually winning?
Free, with nothing to buy inside it.
