Who cares about what they do to themselves. If they dye their hair then let them dye it, Purple, red, orange,pink,highlights, brown, shit stain, etc... If it ain't you then don't worry about how they look, worry about your self.
Seriously Firey? Nipple pierced? REALLY? In my head, I thought you be the person that only focus in school and doesn't get involved into piercing and tattoos when I first saw your pic. LOL
