Hello, nouvellevogue:
For me, this happens in both short periods (as when doing something for a few hours, able to retreat when I need to, I can join in with things that at other times I hate, and behave with perhaps no aspie traits, though people still sometimes class me as weird); and in long periods (months or longer), where I'm not depressed and am focused on something I want to do properly. In the latter case(s), I don't think I seem entirely NT (to myself or to other people), but I don't think anyone would diagnose me as autistic either, just antisocial. I develop passable interests in things like fashion (usually not the one everyone else is following
) and make acquaintances, if not friends. I forget about the things that are so, so difficult and awful at other times, and act pretty normally. Then something goes wrong, and the people I might have got to know a tiny bit put together all the tiny things I wasn't quite doing and realise it wasn't because I'm on the cutting edge of cool, but because I 'have stuff wrong with my brain'.
Is there more variation of this sort in girls than boys (because girls can sometimes fake NT so well, and then it collapses...)? Who writes about AS in girls? Can we expand the stereotype to cover us?
