This is my little brother. We don't have much in common. He is the iron-pumping Abercrombie mall-cop wannabe firefighter, and I'm the flabby library artist granola-tofu-kombucha "hippie". And still, one of the best parts about going home is when I'm standing precariously on the edge of the bathtub with our wonky old hair clippers in hand, and he says, "Do what you want, and then shave it all off". Then we laugh and talk about funny youtube videos while I give him mohawks and devil horns.
Same goes for my older brother and dad, of course- except they are less adventurous with their hair, and instead of youtube, it's talk of old movies and time travel, respectively.
