I've come across the question "Do/did you like to spin in circles?" many times over the past year or so, and I've always answered "no", but always in the knowledge that I remembered doing it as a child; it's just that I seemed to remember it as something that everyone did. OK, not everyone, but enough people to make it not stand out as odd. I seem to remember it happening in the school playground as "just another thing that us kids did" like play British Bulldog or football or chase round for no discernible reason.
What's your memory of it like?
Maybe the other kids I saw doing it have their own adult autistic diagnosis now! Or maybe it was "something we all did." Or maybe, I have false memories and was the only one doing it!
