I'm super laid back and appreciate most people that are making an effort to make good for others/themself. That being said I do end up joking with people sometimes and enjoy goofing off and laughing at other people's mistakes, but they don't get too offended unless they're super uptight. Or I cross the line. Which has been known to happen. But it's all in good fun. But I believe people learn from their mistakes or should and that its all a part of learning and finding out who you are.
I'm kind of nerdy and enjoy/really good at math (hence my mechanical engineering job) and someone that's into that kind of stuff (or any general nerddom) would be fun. Being smart/intelligent is pretty hot. But I do appreciate the artsy side as well even though I know I could never do any of it myself. I try, just don't expect me to be good at it myself. I'll just sit there and look cute (I hope) and support you.
