I'm just a regular Joe who wears khaki pants and a collared shirt. I don't watch TV but I do spend a fair amount of time on the net, reading articles and forums on topics that can range anywhere between:
Kardashev Level 1 Civilizations,
commodity futures trading,
and a whole bunch of other stuff that has nothing to do with anime
I do NOT decorate anything I own with anime-ish things. No wall scrolls hanging in my bedroom, no Belldandy key chain, no Rurouni Kenshin sticker on the side of my car, ect...
When I'm at my local anime con, I'm known for my crossplaying antics amongst a small circle of people but outside of that I blend right in with 99% of the general public.
