Call me old fashioned but I think all guys should have short hair and all girls should have long hair. I shouldn't have to go into deep though to figure out the love of a kid I walk past in the hall.
I'd say 90% of the white/Asian population of my school has long hair and the reasoning for this is unknown to me.
I get a "1" all around when my hair is cut. Which is the shortest attachment on the razor without taking my hair completely off which I intend to do some time.
Long hair looks stupid, and if you do it because you think the ladies like it that way your an stupid. My hair works the same way, when you rub it across the grain it's like an climax in the palm of your hand. Short hair is also super manageable, because you do nothing with it.
