lol. I hope I'm not rubbing off on you, because you sound like me now. I mean, I know my posture is poor. I have more important things to focus on than whether I'm impressing people with the extent of my full stature, and besides my upper back muscles are always sore. But, yeah, people can look at you and tell you're a slouchy "dufus", so you tend to be solitary, and that makes you vulnerable. I mean that only in the most commiserating way, though.
There are many perspectives to look at it from, and they're all pretty depressing. I will probably just accept that my "style" is ugly to most people, and instead look for similar people who either don't care, or don't see it that way. I think diversity is beautiful, and I try to expand my notion of it so that I can see more of it. I have a ton of allergies, my feet are flat, I have lousy muscle tone, my sinuses are always closed, so that makes me sound even more monotone and guttural, and it intensifies the impression I lack self-awareness. But you know what? I'm eventually going to boil it down to "I'm ugly to most people", and then stop worrying about it. It's their problem.
