Haha, me too.
I gave off an aloof or snobby vibe when I was younger. Some people thought I didn't socialize much because I thought I was too good for them. In reality, I was shy and competitive, I loved learning, and I was in treatment for a mental illness. Nothing to do with them at all. I just was more interested in school stuff than in talking to the people sitting by me in class. Same in sports...I was there to do my best and compete, not chat it up. So I felt awkward and shy around the people who teased me for being focused, nerdy, uptight, what have you, and since they seemed not to care about what mattered to me...and I didn't understand what mattered to them...I was all business and people took it personally. Fortunately for me, I blossomed in college, but ive heard thru the grapevine that high school people still remember me as snooty. In retrospect i have to laugh because in reality I had so much shame about myself and how I was different from them...like I was the only one whose s... stank!
Sorry for the rambling personal story.
Anyhow, since I realized what a disconnect there was between how I felt and how people saw me when I was the quiet one, I've found quite a few people who had the same experience. I think your idea is really interesting.
