Some girl are just egomaniacs.
They  go around thinking `all guys are such superficial jerks'
They're so much into thinking that that they pull you into it, and you find yourself
acting like a superficial jerk. You do it half as a joke, cause you cannot believe
that this girl really thinks this is all you are about.
But then you discover `wow! She wasn't in on my joke. She thinks I'm a complete idiot, and
is giving herself a stroke on the ego by thinking of me like  that'
Well.. it's your boring repetitive life.
