It's hella changed since my undergrad days! In the early naughty-oughties, I desired the kid wearing puka shells and flip flops that pulled out his guitar at parties. (I guess I still love the guy who breaks out his guitar at parties. It just depends on what he's playing.)

Anyway.

Around my twentieth birthday, a kindred spirit once told me, "Jenny, you're not going to be happy unless you're with someone who consistently surprises you." It's a statement that has stuck with me. They say we are attracted to people posessing qualities we lack. Keeping some things mysterious and alluring is something I'd like to work on (she writes, in a public forum!). I do think that quality can sustain relationships and keep the two parties from getting bored or restless.

HUMOR. This is huge. If you can't make me laugh, forget about getting me into bed.

COMMON INTEREST COMPATIBILITY. I'm not looking to match him exactly, but like Hornby said in High Fidelity: "It's not good pretending that any relationship has a future if your record collections disagree violently, or if your favourite films wouldn't even speak to each other if they met at a party."

Also - honest, self-aware, intellectual, etc. etc. The usual stuff.
