Do so many women bleach their hair blonde and keep their eyebrows a dark brown?
Folks, the thing I hate in the fairer sex is falsehood. If you have A cups, be proud of them! I'd rather see you have real A cups than fake D cups. If you're a brunette, be proud! I have loved a total of three women in my life. One is my mother. One is my ex-fiance. And the third is my wife. All of them have brown hair, and I love all of them for other reasons than their hair color. For that matter, none of them have the same eye color or body type.
Changing your physical appearance in order to gain favor only gains the favor of superficial assholes who value physical looks over your real soul and personality.
