It occurs to me that I could have just added to CJ's post.

She hit some details that I missed.

"People with Asperger's are generally neat": HAHAHAHAHAHAHAHAHAHALOLROFLMFAYOUARETOOFUNNY.
Are there people like that? Sure. But getting my sister to take a shower on anything resembling a regular basis is a headache, and even then she doesn't wash properly. She doesn't like the way the water feels. She doesn't like brushing her teeth because she doesn't like the way it feels. There was a period when I was in high school (and, honestly, still today) where I will refuse to hug her if she smells. And when I say smell, I mean she reeks of sweat and other things. And her room is, well, let's just say "disheveled" at the least.
A lot of autistic people are touch-aversive, so they don't like the way lots of things feel. When my brother gives hugs, he has to have full-body contact, which is awkward for me. I assume he simply doesn't like pressure being on one part of his body.
My sister, when she was younger,
hated wearing clothes. It took us a few years to get her to wear them. She does it just fine now, though she seems to dislike bras. (But who doesn't?)
CJ wrote:Other quirks of hers:
"Likes to talk only about things their interested in." Gods, if we could get her to talk at all. And if she does talk, it's not exactly about "what she's interested in." It's more "I think this is funny and I will tell this joke every five minutes but I will deny that I am telling it every five minutes." For example, today she went driving with my dad (she's got her permit). She, unfortunately, passed the mailman six times. So when she came home, the first thing she said was "There are TOO MANY MAILMEN. That's all I'm saying." And proceeded to say that "randomly" every five-ish minutes for the next two hours. But if you want to talk to her while she's lost on her computer/in her music, she will scream her head off for bothering her because she does not want to deal with you.
This is the same as my sister, to a T. She talks more than your sister, it seems, but she holds onto things that she finds funny and repeats them often. (Not every five minutes for two hours, but closer to once or twice a day for a year or more, if she sees the person that originated the joke.)
My brother, on the other hand, is non-verbal. He is in a developmental center and they have been getting him to talk more, according to my mom. (I haven't gone to see him in a few years, so I'll have to take her word for it.)
CJ wrote:As for Ronnie being Aspy, well, there's a lot of different kinds, as you can tell by the various testimonials so far. But one basic Aspy trait that I can't tell with Ronnie is this: looking people in the eye. Most people with Asperger's cannot look at you in the eye while talking. They look at other things, other directions, or around you. But I don't think Ronnie does that, or maybe I just haven't noticed.
My sister and cousin are able to look people in the eye. This might be something that varies.
