One
female reading this thinks this
theory explains things quite well --
confidence is
attractive but it also covers up a multitude of
flaws that we don't find out until we're treated like
crap by the confident
bastards.
Luckily, social confidence isn't the only kind; I've discovered that confidence around a hobby, a well-liked job, and other things can be just as attractive and much more likely to indicate a guy worth having around.
