The murderous urges from the previous post are dissipating.
As usual with these incidents, there's a history involving memory. I now realise the guy reminded me of two imperious bosses I had about three years ago. Same manner, similar appearance. And all of them were equally incompetent.
If there's one thing I react badly to, it's being demeaned by an idiot. Fortunately the people who insult me online are at least good at what they do.
Going further back in memory, I can see that much childhood was about being pushed around by morons. Mainly parents. If only I had had kids of my own, I would have had a shot at being one of those morons. That might have balanced me up.
