I've wanted to dye my hair for YEARS. When I was at school I wasn't allowed and then for the last year people have been saying "don't do that, you have beautiful blonde hair". Also I figured I wasn't bad -ass enough for pink hair. Also I figured in years when I have kids and they look back at photos of when I was young they will mock it. And then I wouldn't be able to tell them to be sensible.
Then I remembered, I want pink hair.
So I did it.
