Hell, one can even arise at this observation from patterns witnessed in the real world.
I'm thinking of two polarized things/events/situations, one in which involves an abused dog that my sister brought home, she was one nasty bitch, and it took a full day for my sister and her then bf to catch her, they both were bit and snapped at several times, but finally they got her and she, "Scruffy" became our dog until the day she died, she was one mean old crotchety, aggressive bitch, she only fully trusted my mom, but we all understood why, she must have been severely abused by someone or by quite a few people, her aggression was a tactic to ward off potential danger to herself, (she was quite small), so this kind of aggression, at least to me is more understandable, it is fear based, and trauma-based but once the victim gains your trust s/he will no longer be aggressive towards you, and that's a beautiful breakthrough!
The other situation I was thinking of was something I've seen my entire life, peacockery to the point of implicit bullying, acting in a way because you know you can, showing off, putting down, silencing the crowd so you can secure the stage, what's shocking is that women/girls can even do this, but it is usually done by boys/guys/"men", but, AHAHAHAHAHAAA, they're always dumb, tis true, they are.
Oh shit, there is intellectual peacockery too, oy vey this is the worst, it's when someone has an IQ in the 130 to 160 range so they're in between being a god and the masses and they love to look down at and put down their "intellectual inferiors".
The smartest people I've known my entire life have all been so intellectually dexterous and humble.
The more you know....
This is a question I tend to ask all the people in my life, it is a defining question, and it's this:
Would you rather be the biggest fish in a small pond, or a small fish in a big pond. If they answer the latter, then they're my kind of people.
