I mentioned it as a possiblilty to a friend who I'm convinced is more Aspie than I am, but he didn't seem interested, so I quickly dropped the idea. Though I do occasionally remark that what he's just done seems a typical autistic trait. When I told him of my own DX, he said that he didn't think there's anything in it, whatever that means. Since then I've explained a few things that suggest AS gives me some very real problems, but I don't know what he makes of it. He never complains of bad experiences of the Aspie kind, so I have little choice but to assume he's content seeing himself as NT, though judging by my own observations and those of others, he's anything but neurotypical.
I often feel tempted to tell another friend of mine that she seems to have a lot of strong Aspie traits, but so far the mood has somehow never felt right for me to do that. She's had a lot of stick from people who know her, but lately claims to be doing better. I think the best thing is for me to say nothing unless she comes back with more tales of social failure. Cockney Rebel is probably right about the risk of wrecking perfectly good friendships, and I don't know this lady as well as I know the guy (he never seems to get upset), so while she's not obviously broke, I'd best not try to fix her.
Then there's my wife, who scored as a mixture of AS and NT traits in the Aspie-Quiz. There are certain disturbing features of our relationship that suggest she's either autistic or extremely insensitive, so it's probably important that she looks at the AS theory seriously, but she doesn't seem to want to see herself that way. I've done no harm mentioning it, but like with the guy I mentioned, it was like talking to a brick wall. Weird thing is, she once diagnosed herself as dyslexic, I told her I believed her and offered support, but she hasn't mentioned it since, and AFAIK she hasn't tried to get any help for it.
