As an INTJ, I've considered my temper or getting angry analogous to an earthquake. Earthquakes may have pre-shocks, but usually they don't. They hit, (not very often), and can sometimes cause incredible destruction. And then it's over. A few aftershocks, perhaps, but life goes on. The problem with earthquakes is that even though they may only last only a minute, depending on how strong the earthquake is, it can still cause immense damage which may take a long time from which to recover.
And that's sort of like my temper. I don't get mad or angry very often. Frustrated yes, irritated yes. But truly angry? no. However, when it does happen, there's generally not a lot of warning and it is scary at how fierce it is. Like some people posted, I get very sarcastic, biting, and sometimes even cruel. But then it's done...however, depending on how angry I've gotten, it isn't the same between that person and I. Actually had an ESTJ say something to me which was not well thought out AT ALL. Being exrtraverted, I don't think he gave much thought to how truly insensitive it was, or how truly insulting it was. And I got ANGRY and let loose. (after about 10 mins of being in shock) Again, very brief...but our relationship won't be the same....which is sad, but I don't regret losing my temper. Again, to continue the analogy....after an earthquake , it takes time to rebuild the complete and total devastation that has occured.
I don't think I ever felt true anger until I was around 21...when I learned people who are told what they want to hear and believe it will often become poisoned against you when
you when you don't think you have to do it too. Sorry but that's pretty fucked up.
I frequently get irritated, but I never show it. I don't usually even vent to people I know; I usually successfully rationalize the irritation or potential anger away.
But there have only been a few occasions where I really got angry, and it was immediate. I had no time to rationalize. It was bizarre. I felt rabid. I just channeled all my physical strength everywhere and anywhere, and I had no clue what I was doing, when or if I'd stop. Hospital visits ensued. And not mine.
And then, each occasion, I got extremely run-down and fell asleep for at least 30 hours...very bizarre. I remember waking up once with one guy's blood in my nails and on my knuckles. Really gross, and I don't want it to happen again.
(That was when I caught a "friend" violently kicking my dog.)
