Not an intrinsically naughty or bad kid, no. Prone to violence, yes.
Got taken out of school for a bit for various reasons, perhaps the worst being when I waited patiently for a certain kid to pass down a walkway where I was perched with a brick which I proceeded to break his skull with. I was six years old.
Around that time there was still much stock held in being 'cock of the school'. My nutter status meant I was unchallenged until the final year when a bigger, stronger kid with an impressive criminal pedigree joined. We used to 'play army' in those days, which was in essence toned-down fighting. For me, however, it was an excuse to wait for the right moment to jump on the back of his knee, knocking him face-first to the floor. Where I proceeded to reintroduce his head to the floor until a teacher pulled me away. Hard man, eh?
The fact that if a kid's father even so much as raised their voice my dad would go round and deck them certainly did a lot to reinforce this. Oh, and once a girl scratched me. Since I wouldn't hit a girl, my sister did the honours in style - went round, knocked on for her, then produced an iron bar she could barely lift and wrapped it round the girl's face. Now
that's style.
I was taken for all sorts of tests and my IQ 'ruled out' autism (this was before AS was diagnosed in the UK and the ignorance was even more so than it is now) but found that I exhibited enough schizoid personality traits to be considered a future mental health risk and ADD was suggested.
The rest is shrouded in mystery because the only person who knows for sure is dead, but my ritalin prescripton came and was withdrawn after my mother read a scare story.
What changed me? The IQ test meant I was no longer a violent misfit but a 'gifted child'. So the school that wanted rid of me suddenly embraced me, and I was allowed concessions like going to the library on my own with specially-prepared lessons rather than have to suffer the 'baby work' the main class. Before that? They used to just stick me in with the deaf kids. No joke.
So - suddenly enfranchised, nurtured and encouraged (plus with the aid some excellent social engineering from teachers who'd sit me with the most middle-class kids so their influence would seep through), not to mention my grandparents, who looked after me for a while, I was eventually calmed down. Or at least taught that violence would get me killed or locked up if I carried on.
By the time I was hastily enrolled in a sink-estate comprehensive (on the fucking day term started, no less) things had changed, but there's another few paragraphs in there and I think the above is enough.
So yes and no, really.
