Growing up, your little sister probably watched She's All That or some such chick flick where the ugly girl takes off her glasses, and lo and behold, she's dumb fine. While glasses and a ponytail don't make you ugly (and, in fact, when combined with a tartan skirt and white button-up, do wonders for the libido), trips to the dermatologist, dietician, and pilates instructor can change everything. Beware you horn dogs of the night, she might be talking to you just to show off what you missed. If she denies you, you probably deserve it anyway, for fixating on the girls who matured at 13 (and who now...well, we'll get to that).
