Someone cool. Not "sunglasses bad ass" cool, but a composed personality. Obviously it'd be somebody you trust... I think they'd have a rather mature side also. I think you'd fall for somebody you find yourself immensely comfortable around and you could tease each other a lot. You'd fall in love with somebody who's able to interpret and appreciate the things in life similarly to you, but who could also change your perspective in new ways without intention. They'd make you laugh, a lot.
