I wanted my hair cut at the same time - and I enjoyed it.
Unfortunately, every other girl at school had long hair and a thick fringe with pretty hair clips and bands. So my mother decided to let it grow - or as I prefer to term it, never pay to have it cut again.
I never had pretty bands - she used rubber bands that stuck in my hair through the day and overnight and I remember screaming and yelling as she ripped the brush over my head every morning.
When I was 9, my granddad asked me what I wanted for my birthday, as I didn't get presents from anybody. I said 'a haircut'.
I got a short back and sides and loved it. However, being assumed to be a boy angered her, so I went back to long hair afterwards, other than a brief period of undercut and from 21, colouring it whatever the hell I felt like.
These days, it's long, but DP cuts it when it gets past my bra strap - mainly because I was told by my mother on my 40th birthday, I had to cut it short like she did. She suggested I went to her hairdresser (she'd gone every 8 weeks throughout my childhood for exactly the same style), as she could make the woman cut it to an inch and a half long and perm it on tight rollers, even though the hairdresser didn't really want to do it.
Anyhow, venting over - buy pretty clip in slides and 'enjoy' how easy it is to get headlice out.
She'll like it again.
