That's usually how I start introductions, since it's something I can be pretty sure of. The name on my birth certificate isn't the one that's on my school records and legal ID - different first, middle, and last. I've had occasional moments of panic over the fact that the only thing supporting my identity as I know it is a copy-of-a-copy of a birth certificate that was never officially filed and thus has no legal value. But the Jess part is certain.
Facts I like to trot out at introduction times: I once had a carnival ride collapse on me. I know how to butcher a moose. I have detailed plans for how I will survive the zombie uprising. I've rowed two marathons. I've been a professional construction volunteer and archaeologist and barista and text-messenger. Now I'm a student. I'm not exactly great at doing things in order.
I spend most of my free time reading or eating. Somewhere under those priorities come drawing, playing World of Warcraft, and refreshing my lj friendslist. Sometimes I write. Sometimes I crochet hats with Mardi Gras beads. Sometimes I talk a lot about New Orleans, because after four years this city still amazes me, and I like to share.
