Is AUTHOR wrong in the post ? POST : So, my daugther will be turning 17 in a month and wished to dye her hair turqouise/blue for her birthday.
I honestly don't see a problem with that, hair dye is temporary and she's old enough to decide what she wants to do with her hair.

Well, my wife disagrees. She thinks it's a sign of teenage rebellion - I told her I doubt that since my daugther asked us if that would be and acceptable present - and is worried people will think she's "rowdy" and that our family will look like we have problems. 

I tried to talk it over with her, but she thinks it'll result in her grades getting worse and her slacking of in general. (I really don't see the connection.)

I love my daughter and know how badly she wants to dye her hair, so would I be the asshole if I just took her to get her hair dyed for her birthday?
