Personality-Wise: I generally hope that they have a good sense of humor, have a happy outlook on life, and is someone who likes to have a good debate once in a while. I don't like when they agree with everything I say. Also, obviously, they need to be kind to me AND others.
Appearance-Wise: Lively eyes, taller than I am, which is five foot three, and a nice smile. Not super skinny, but slim with some strength behind it. Someone who cares somewhat about his appearance, but isn't obsessed with it.
As you can see, I like a nice, happy medium.
