I am simultaneously relaxed and intense: always thinking but rarely worried. I am no sycophant, and I'll tell you what I think. I won't ever take a moral high ground but if you can't back up your opinion I won't be gentle. I hang out with people who call me on any bullshit, and I will defend what I say until I'm convinced otherwise (which I am, regularly). I love it when other people do the same.
Other than that? A litany of success punctuated with abject failures. Getting a massive pay raise. Running out of money at inappropriate moments. Reading ALL THE TIME (I run a reading group + have minor dalliances with the classics on the side -- note I've now mentioned reading twice). Walking into people on the tube because I'm reading (thrice). Going to the shop to buy dinner and wandering around with a friend for 45 minutes and leaving with no food and a bottle of vodka. &&cc
I know lots about good video games and literature. A bit less about film, music and art.
Speak your mind and speak it loud. I like opinionated people, but love those who are opinionated, know their stuff and don't get sidetracked in conceptual mire. i.e. if you haven't fended off the postmodern dragon by now then I'll probably be bored. Also: feminism = humanism/common sense. Don't believe that (or something similar), we probably won't get on so well.
You think we would click. I am always silly and ready to make a joke, but they are often about very serious things.
