Mom won't let me cut my hair?

I am also a 15 year old girl and have the same struggle with my mum, somehow, she still thinks I am 4 and should have a lovely straight cut bowl bob. It just doesnt work like that. Tell your mum that in order to grow up you have to experiment in the teenage years of your life, because otherwise if you don't do it now you will feel you missed out and do it when you're older... And then people will actually think you're weird. I don't see how band t's relate to smoking pot but it's just expressing your musical taste..
