I've never found you to be obnoxious. But then, I also tend to hermitage in fear of coming across as obnoxious. In fact, my tendency to hermit is strongest after someone vehemently, or even just strongly, opposes something I've said or done, because my first assumption is that I've been offensive. I can entirely see where hermits might be those who are "painfully sensitive".

Invisibility is tempting. With the kid around now, it's VERY tempting - the last thing you want to be is *those* parents/*that* family/*that* kid.

My self-perception doesn't seem to line up with anyone else's perception of me, either. I think it's a pretty universal human trait.
