DH is 33, I've cut his hair with clippers since we got together when he was 24, before then he did his own hair with clippers.
AIBU to think that maybe the time has come for him to stop getting a grade 3 all over and actually get a hair cut for the sake of £6? His hair's thinning a little bit and he's got a proper professional job, I just don't think a buzz cut is appropriate any more.
