Yeah, I've been misread a lot too.
Also, in 10th grade, I would often when walking through the halls, run my hand along the walls and lockers and stuff, something I'd always done up to then. Except by then I'd gotten an IEP, so the director of special services would go up to me and make me stand still, to "calm down", while ignoring that I said I was fine, and ignoring my questions asking why she thought I needed to calm down. I had forgotten this until the March IEP meeting, when she brought this up, though of course to her it was totally obvious that I was STRESSED OUT at these times - even though usually I was writing poems, that got interrupted and forgotten during these times.
BTW, as far as having things misinterpreted - why is it that in an animation class, where students often go under the desk to work, to relax, to listen to music, to get away from the fluorescent lights, it is normal for an art student to go under a desk and unwind or even sleep, but when an autistic art student does it it gets seen as pathalogical, and suddenly you have the nurse and the director of special ed touching you and talking at you and then noting that you are "especially sensitive to touch at this time".
Seriously WTF! Darn right I'm sensitive to touch when people intrude on my space without bothering to even ask me if anything's wrong, whilst ignoring the other students who are also under desks or on the floor!
