I have never understood barber etiquette. As I see it, a trip to the barber's is a professional situation - a business transaction, nothing more. I am a man who wants his hair cut. The barber is the man to do it. As long as we are both polite in our dealings, the encounter need not lead to friendship.
As someone who has otherwise had the same mid length brown hair since I was four, the fringe was my little bit of statement, the only proper 'hair style' decision I have made - ever. But most of the time I wondered, as Kate is no doubt find herself doing soon, how wise a decision a fringe actually was.
