Getting Angry on the Phone

If you know me enough, you don’t see me get upset so much, well, at least on the way I’d get aggressive. Well, but I guess everything has exception…
I won’t tell who it was at least for now; bottom line is that it’s not someone on my friend list here, but was not a stranger.
It’s just so amazing how people manages to annoy me telling me what to do without even knowing what’s going on. So just a second or so after he completed his sentence, I felt rush of blood going up to my brain, and next thing I notice was that I was pretty much 60% yelling at other person on the phone. It was only 60% because dominant side of myself was still holding “angry myself” back, sort of speak. I do occasionally get angry on the phone, say at tech support representative, but one that I experienced today was just outrageous.
It occured to me, that I guess those people who don’t know when to stop, those people in Japan who are known to “kireru” (キレる) don’t have dominant part of him/herself.
I only hope that this person I was talking over phone won’t make silly statements to me again, because I wouldn’t be 60% next time.
