Anger and I are pretty much strangers. In the past 11 years with this employer I've only gotten angry enough to publicly chew out someone once, and it was the unmitigated narcissistic effrontery of someone who decided to read through and change a lawsuit-potential news story that had been carefully read and vetted by senior editors and lawyers that set me off. He wasn't a copy editor; it wasn't his story; a lawsuit on the topic was already filed; he was playing with matches in a dynamite factory.
It was not unreasonable for me to be roaring-bull, mad-dog, charging-rhino angry.
I don't like to do that because it leaves me nauseous and guilty afterwards. I guess it's like INTP social remorse, letting an emotion run the show briefly and also letting it drag me out of that safe introversion mode.
On the other hand once was enough for the newsroom, that particular behavior has never been repeated.
So occasionally anger serves a utilitarian purpose, but it comes with a cost.
