I might not realize I was in an argument until it's over. I'll correct someone then get mulish about asserting my point. Things like expectations or when an argument is over don't matter. I'm not that deliberate. It boils down to me thinking something they said or did was wrong/inaccurate, so I push until they give in. Later, when it's less immediate, it's easy to see what happened and how I should've just let it go.
Sometimes, it can be enough to find out why our perspectives doesn't align. Realizing that, even if our views can't be reconciled, I can respect where the other person is coming from makes it easier to work around them instead of arguing with them.
I'd rather watch others argue than do it myself because I learn more from that.
