For some reason I had dismissed the idea that my husband had AS for the longest time, but then I joined here (because of my kids, who are autistic) and I'm finding so much of what I'm reading on here matches, that I'm starting to suspect it. My husband has a pretty static default facial expression, which looks kind of angry but at the very least, serious. That's all the time, no matter who is around. But...
His body language is also extremely awkward, in public, but it's a lot more natural when he's at home with people he's comfortable around. In public his shoulders are very stiff and he holds his arms strangely. They can't be by his sides; they either have to be crossed in front or clasped behind his back (the latter is less standoffish). He sits really stiffly too; he always looks really uncomfortable even if it's a comfortable chair. But at home, he's nowhere near as awkward. Sitting he looks relaxed, and his shoulders are not stiff. He still does the weird thing with his arms though. He's the shyest person I've ever met, so prior to this thought about AS, I always just thought that was normal shy behaviour. If it changes from home to public, would that be shy? Because AS would be like that all the time? Or can it change like that?
