Almost everyone I know has a favorite one, cept the exception of this one friend I have who never makes up his mind.
One day it's spikey and brown, the next it's lightly slicked back and blond (and his eyebrow ended up a little bleached, too. XD), and then the next day it was back to spiked, but black with red tips.
Seriously. XD
Mine depends on weather, but right now I'm keeping my hair down because it's so friggen cold in my house. -.-
