No, I hardly ever lose my temper. Even when I do, although I feel very out-of-control at the time, postmortems usually indicate that my response was fairly measured and reasonably socially acceptable.
I'd probably be a lot worse if I didn't habitually avoid over-stressful situations. But even while I was living in the pockets of a partner who was stressing me out with her pathological behaviour, I never lost control. I kicked over a coffee table but broke nothing. She had an anger management problem, and I got so sick of her having this freedom to rant over the top of whatever I said, this bloody-minded angry voice ripping at me while I copped for all the hard work of trying to keep things on an even keel, that I found myself joining in, just to get even.....it did no good, but it felt good at the time and I think I'd have burst without some kind of outlet for it. But that's not a bad temper.
I can have bad moods where I shouldn't talk to weaklings because I can only express negativity, as it's all that occurs at such times, and it drags the weaklings down with me.......one day I might meet somebody strong enough to withstand my cynical attitude and actually help me pull out of it.
The problem is that I'm wide open to becoming passive-aggressive, because I'm so reluctant to flare up and be actively aggressive. Therefore, assertiveness is vital to me. If I make it clear what I want of people, and engage with them, complain, remonstrate, persuade, argue, put my foot down, negotiate, etc., then there's no need to get sucked into game playing.
