Some other Aspies. I discovered that there were two others in my little social circle when I disclosed my diagnosis, and another is seeking diagnosis. A few of the others might be said to be a bit eccentric or unconventional. The more conventional ones are the kind who don't have to strain themselves to tolerate the eccentric ones. All are characterised by not being people who care about the social pecking-order much, and having a straightforward way of communicating (I don't mean always literal or without humour, but no stupid mind games.)
Mothering, wanna-fix-you types? Yes, quite often especially when I was younger, and usually more romantically than friendship-wise. But looking back, I can see that I was doing a pretty good impression of a lost puppy a lot of the time, so maybe not surprising. Data may be somewhat skewed by the fact that I have no idea when someone is attracted to me (though trustworthy sources inform me that it has happened!)
Oddballs? Often, yes. I was a junior member of the Not Admitted To Any Other Club Club and never gave up my membership. Everything from super-swotty, middle-class maths geeks to the dyslexic council-estate lad who got bullied for enjoying "girly" gymnastics in the playground. There are folks that treat people nicely, and folks that don't; I'm too lazy to categorise people by any other of the multitude of characteristics they might have. Making friends is hard, but there's more chance if you're tolerant yourself.
Bus-stop proselytisers etc. - oh, yes; always. And if there's a huddle of school kids on a street corner looking for someone to be cheeky to, I brace myself.
Truly nasty people? I was a bully-magnet at primary school; less so as I got older (probably just because my masking improved.) Very rarely in adulthood - though to some extent, the good people that I know help me to know when I should be a bit careful.
