Speaking as one, I have found that I have never gotten "grace" from most folks. A few folks have been especially patient with me, over the years, and for that, I'm grateful; but they haven't been the norm.

I used to go to Japan, quite often, and watched Americans violating societal norms, all the time. The Japanese were usually fairly good at not lashing back, but I could see them visibly restraining themselves, sometimes. Over the course of about a decade, I learned to at least respect their ways. I found the Germans to be less accepting of annoying Americans (and I was one). I learned a lot quicker, there.

I know that many folks think that self-diagnosing as "on the spectrum" is considered some kind of "get out of jail asshole" card, but that's just an urban myth. If you're an asshole, you'll usually be treated like one; no matter the reason.
