It's simply not.
Diagnoses is getting better, so a lot of people very good at masking have been getting diagnosed. Those who weren't as good at masking you likely wouldn't of seen as much.
And don't forget you were an aspie kid, I at least was so focused on just getting through every day I didn't even notice the level 2 kid and his aid in my class. I don't even remember most of the kids at all.
My guess is you didn't notice.
