We agreed he needed a haircut before school starts and he has had nice short cuts in the past which is what I expected but, to my horror, he brought him home from the barber with a practically shaved head. He is only 4 and I would only shave his head if he had lice or ringworms or some other disease of the scalp. It's also getting colder so I wonder why he thought this was a good idea. AIBU to be really annoyed by this?
