When I was younger I had a habit of talking too loudly, especially when I was excited. It was helpful sometimes, like when I was asked to read out loud in class, but if I was in public with my mother and other people they'd get embarrassed and tell be to speak more quietly. I don't have that problem as much now, for some reason. It just seemed to start getting better after my Asperger diagnosis.
I also say very brutally honest or blunt things online that some people find worse than annoying. More likely they think I'm an evil rhyme's-with-witch.
But that's *their* problem. They get shocked by someone having the guts to tell the world the reason why something like a TV commercial sucks, but they're not shocked when that same commercial is lying, fear-mongering, guilt-mongering, or is just plain awful.
