I'm not a teacher, but I used to probably be one of these people to the staff of every school I went to lol. Source: am a sociopath
Nobody ever really understood me as a kid and still don't now, I have multiple mental disorders(bipolarity, being a sociopath, I had gender dystopia when I was younger though it's fixed now)
I recall beating the shit out of numerous kids my age when I was very small (4-8 years old) and not even feeling bad about it when they took my shit (or tried to) that I was playing with, or if they wouldn't share what they were playing with.
I remember one of my preschool teachers stepped on some blocks I was playing with in the corner, so I kicked her shins repeatedly and I supposedly made one bleed. I heard she quit not long after.
I used to steal things a lot, I would never get caught even if people would suspect me, which was very rare. Nowadays if I want to do something like that I don't even need subterfuge because people are so easily won over, but I rarely even express my sociopathic tendencies now other than lying. I do love lying.
I also used to convince other kids to do things for me that got them in trouble quite a lot.
These kinds of things used to be harder to get away with mostly because I was male back then but I've always hated being male and my mind has always worked on the xx side of the spectrum so now that I'm physically on the same wavelength of my mind it's very refreshing. It also makes my lying and manipulation far easier, being a charming, social, cute girl that nobody suspects rather than an outgoing, handsome, trustworthy, intelligent guy. It's not why I switched, since it has always fucked with my mind that body/brain don't match but it's certainly a bonus.
That's getting off topic though. I'm unsure if I would still be considered one of these nightmare kids by these teachers that don't actually teach much, because I don't do anything directly anymore, I only have other people do things, but I do wonder if anyone realizes.
I will likely get downvotes for this, because people downvote all content they do not approve of, but I don't actually care much.
