7 year old dd went to play at a friends house yesterday. Dd had long bum length hair but when she got dropped home friends mum (a hairdresser) had cut dd's hair into a shoulder length bob! I didn't see the mum as she just dropped dd at the door and she came in on her own. I am so upset dd had never had her hair cut it was lovely, I know I can't do any thing about it now and dd is happy with her new hair style. AIBU to think friends mum should have spoken to me about this first?
