Yeah, well, you don’t.
Don’t argue it and bring it up to death, even on principle alone, (unless it’s something you feel SO strongly about that you will divorce them unless they somehow see your reasoning and agree with you.)
Pick your battles.
I picked the wrong one last night (again) and kind of feel like an ass idiot.
You live and you learn.
And I’m trying to learn to bite my tongue when it’s not a big deal, or even if it is a big deal but not worth getting into a huge fight over.
