I've still got a lot of readjusting to do (I'm super, accidentally rude by US standards) but my dog and I are making great cultural strides. I no longer (usually) jump in surprise when people are nice to my big, black dog and have stopped saying "thank you" in Chinese, mostly.
My time in China left me with an obscenely large DVD collection (all totally legit ((why isn't there a better way to imply sarcasm?))- and covering most genres. I love classic monster movies, fun and clever scifi, horror, documentaries. Pretty much all of it. Oddly, China also left me a deep and abiding love for Belgian beer. Summer wheats and thick, dark winter dubbels. I love them all. I can't do theoretical chemistry, but love the practical chemistry of beer. And I'm making a good faith effort to learn to appreciate American beers again, but it's an uphill battle. My hobby got a bit out of hand in China and on the side (I was a cultural consultant to the city of Shanghai) with a friend, I started China's first beer magazine. It was amazing.
I'm pretty constantly making jokes or saying inappropriate things when I'm not in Cultural Consultant mode. I laugh at really terrible things - like the word doody. I love to sing, but am absolutely awful at it. I play no instrument well but love to sculpt and only occasionally sculpt things out of spite. I once restored a classic 1969 VW Beetle. I loved her, but sold her when I moved overseas.
I am a hopeless nerd about many things and a serial hobbyist. I've done or am planning to do most of the artsy type things. I occasionally play an old school table top RPG, and can probably quote the entirety of Ghostbusters.
Oh and I love to travel and attempting new languages. I've been all over Asia (except North Korea and Laos and Cambodia). My favorite place on earth is Slovenia. The entire country
