Up until recently, I thought I was faking it rather well and appearing normal to the rest of the world. Now I realize that I don't. Partly, it's that I dress differently than most people, in a way that connects me with my culture and my ancestors. But mostly, it's like I'm on a different continuum most of the time, and most people sense that (having social intuition, and all).
I also totally relate to Elderwanda's experience of feeling invisible. That's been going on for most of my life. I'm not sure what it's about. My working theory is that I'm not in synch with most people, and they don't want to work to get in synch with me, so they generally turn to my husband and address him. When I try to get in synch with people, it's pretty much a failure, because I'm just trying to mimic people and they can tell that too.
It's kind of humbling to realize I haven't been faking it nearly as well as I thought I was, but on the other hand, I can now turn my attention to other more, um, fascinating topics, which I'd be really happy to talk your ear off about if you gave me half a chance, but now that you've been warned, you won't, but, anyway, it's okay, since I'm not the only person around here with that particular personality trait.
