I have just about been the one to make that first move, maybe 25% not.
So I think not a bad track record.
It really does depend also on what was said, and how badly things turned out.
Even when I know I am not in the wrong, I just have to say something most of the time.
If I thought it would do more damage to say something, that it would or could be taken badly....then I have backed away.
There are people like say my brother who all his life has believed he is in the right, so that's a no-win situation, and by giving in one will just make him even more difficult to deal with.
Plus, it doesn't help that person at all.
