Cover art for Come Undone lyrics by Robbie Williams

I thnk that the line: "They're selling razor blades and mirrors in the street" is a really sad reflection on society. The first thing that it makes me picture is an insecure teenage girl sat infront of a mirror, holding a razor blade and punishing herself for her reflection. She bought them both from the same "street", showing that society not only gives people the motivation to pull themselves to pieces and torture themselves, but also the means to.

@CandyCat I'm sorry to say that you're wrong; he's refering to cocaine and his own addiction.
