"...Dear Rae's mom, let her dye...
SO, how old is this girl? Does she have to worry about a job? Probably not. What's wrong with having crazy hair? When I was in high school I spiked my hair and did all sorts of crazy stuff with it and even though I think it was silly now, I thought it was cool and loved it then. She'll eventually grow up, but right now she can be crazy. So why not let her?
