Apparently, I do tend to have the "superior scowl" when I walk, which is actually just what my deepset eyebrows do when I'm lost in thought, which I usually am when I walk.
I do tend to walk quickly, even to the point of pushing other people out of the way. I assumed this was 3 -related. I MUST GET TO THE ENDPOINT.
As to sunglasses, I hate 'em. If I buy a pair, I lose it within 24 hours. I don't see the purpose behind them, either--my irises can adjust to bright lights, and it's ok for them to do that. So I can't attest to that part of it.
