Reply #52: I was about that age around 1972.

And prettymuch ALL the kids, boys and girls alike, had long hair. Mine was longer than that.

The question is, why is your school insisting on a cut? Who at your school is insisting? If as the last poster suggested it is for reasons of safety (unlikely in a kid so young) the school would have a point. If it is because the school feels it is "inappropriate" for boys to have long hair, whereas it is fine for girls to have long hair, I'd contact the ACLU. If it's just some teacher deciding he or she is going to be local dictator, there may be a recourse available to you in the school board. I mean, you may be able to appeal the decision; worth an email, anyway.
