Using Disagreeing Appropriately in Adult Interactions

I realize that I have been unconsciously trying to explain the skill of disagreeing appropriately to my mom. There is no end to the pushing if she doesn’t get her way.

In my version, I’ve said generally if pushing 3 times doesn’t change the person’s mind, drop it and move on. And that most times you shouldn’t even get to 3 times, that’s a last resort if it’s super important to you.

For adult interactions where theoretically a disagreement could be more critical, would you still always say drop it and be okay after one appropriate disagreement?
