Man, I remember high school, and I’m sure glad to be rid of it. You’d probably like something recent, though.
There was someone I knew at a different job I had many years ago who was a real ass. He always spoke in a loud, booming, three thousand decibel voice, trying to sound like he was the Voice Of God (which he may have well believed). He had a major bookkeeping role in the organization, so that a lot of numbers passed through him in a way that would affect what the department was doing for a while.
He was also thoroughly nasty and dumb as a brick.
However, if anyone argued with him, he would spend about 15 minutes chewing them out (in a personal manner) at the top of his already over-the-top voice, then take it to the manager, without ever addressing the actual issue or watching any inputs.
Finally, I figured out how to deal with him, because my son turned 3. And it hit me; this was the behavior of a 3 year old. Not too bright, tantrums, won’t listen. And maybe the same behaviors would work. Be firm, but gentle. Don’t yell or escalate. If the 3-year old rants, just stand there quietly and let him finish. Remove him or yourself from the situation, then at the end, quietly and firmly reiterate the original position, and don’t give in to the 3 year old.
Surprisingly, it worked, and I had a lot fewer arguments with him, and a lot less stress in my job. (He didn’t change). I always smiled mentally, because I never let on, but always thought of him as the office 3-year old.
He was one of the things I did not miss at all when I went to a different job.
