H'mm...Over the years, from eight through thirteen, the friends I successively made were five girls whom now, in retrospect, I identify as aspies or aspie-ish. We were together by default: no-one else would have us. We got along well then, but as I grew up I seemed to become more socially skilled than they; also, in the natural way of things, as I've grown older I've come to care more about really having things in common with my friends beyond social deficits. I still have an idea how three of these girls are doing. One is very awkward and odd, so that I feel pained for her but also slightly repelled, the way a sympathetic NT might feel. The other two are also noticeably awkward and odd, just less so, and are into the Harry Potter alternate universe, 'fanfic', 'shipping', cheesy fantasy novels and films and so forth. The one who's still my friend expects me to share these enthusiasms, but they're just...too juvenile for me, really. I mean, I do dabble in that sort of thing occasionally, but it's for a laugh; I don't take it seriously the way she does. A lot of the novels I like are basically the thinking woman's slashfic, but they're still Serious Literature, and then, here I am developing an interest in formal logic and film technique and so on and my aspie friend isn't advancing that way. Sometimes I take over for her in social situations the way my NT friends do for me.
When I was in high school there were a couple-three aspie or aspie-ish boys I knew, and I got along better with them than with the aspie/aspie-ish girls, because even though I'm a girl myself I found their perseverations more interesting and their humour more enjoyable. We 'got' each other up to a point, and would bounce jokes off each other, but we didn't become friends or anything close to friends; they hung out together and I made friends with a few nice NT girls. Currently I find my most congenial company in highly academic older adults.
