I have a bit of a dry sense of humor, I'm quick to make a joke, easy to make laugh, and always up for random adventures.
I'm the kind of person that loves to learn to do new things. Like, when I was in undergrad, I found the sheet music to "To Zanarkand" on the ground (this version: http://www.youtube.com/watch?v=-qAK3TW7vKo), and decided I wanted to learn how to play it on the piano. Never had played the piano before, but it seemed like a good idea. I discovered most of the things I love to do in similar ways.
Oh, and I love semicolons; people that can use them effectively are awesome.
