While physical attraction might initially draw me to someone, my opinion of someone's physical attraction is so tightly connected with their personality that as soon as I know them at all my estimation of them changes. I can remember that I found that jerk attractive before I met him, but I can't figure why I would have, he looks so stupid now. And vice versa, this guy didn't attract my attention to begin with, but now that I've met him he looks really cute. It's useful because it means if I fall in love with someone automatically I'll like how they look. I wish it worked the other way as well though, life would be so much easier if ex boyfriends were ugly.
