My 1st and 2nd Grade teachers couldn't stand me, but at the time the only thing everyone had in mind was that I had some kind of ADHD, AS wasn't in the picture at the time.
Some teachers thought I was just eccentric or annoying, as for AS, none that I can recall of, actually. In my area, I'd say AS as well as autism in general, isn't well-known. I mean, for one thing, in my AP Psychology class, even though we extensively went through a unit or two regarding mental illnesses, autism/AS was never mentioned. My first best friend was a bit weird, but he was totally up-to-speed with social stuff, making friends with more people, while I always just the outcast of the class. Can't say I could really look back and pick out a specific classmate that I thought would have it. So I would guess that the teachers probably didn't know enough of AS, if anything, to suspect I had it.
