not shaved but cut short (when I was young three centuries ago)
went on a school trip aged 11 to channel islands - who we thought was owner of hotel walked in to our room one night in plaid dressing gown, leather slippers, short haircut
being well drilled we got up off our bunk beds and said "good evening sir"
turned out it was our headmistress, Sister Augustine ... didn't recognise her without her habit on ...
god how we sniggered afterwards
poor woman
(although she was a bit of a cow come to think of )
