The problem is once you get into concrete specifics, you enter the realm of legal liability and potential libel, so it's all posturing until their adrenaline runs out, then they'll either reconcile (or not) behind closed doors.

You know, I think you're right. I recant what I said earlier. I actually don't think I should care about this matter at all.

In a more general sense, it seems best to me that people should just mind their own business and settle things like adults without giving into this pervasive and strange desire to be vindicated by their framing of the situation to others.

There is literally no benefit to anyone but the storyteller. They are either seen as more or less virtuous by their framing of the situation.

They have an interest in telling you a story that makes them look good and a greater interest in downplaying their guilt in the matter. At the end of the day it means very little to most observers.

Pair that with the absolute disincentive to provide actual specifics, the whole thing is moot to an honest person.
