The exposed loos were a novelty for me, at school we at least had shoulder height partitions - but we had communal showers and baths so it wasn’t a huge leap.
I also spent a year or so living in a studio where the loo was in the kitchen area - we at least installed a curtain.
I dunno, I've no problem with communal showers, or nudity in general, but partition-less toilets feels like a bridge too far.
On a trip I took with my father-in-law, the first morning he waltzed right into the little hotel room bathroom while I was showering (in a glass shower) and proceeded to sit on the throne and take a crap. I was confused at his lack of basic respect for privacy, and then remembered he'd been a US Navy guy for many years. Military folks just get used to no privacy in such matters.
eighty...ies? eightieies? why not just "80s"?
Edit: I realize you are probably trying to help them learn. Carry on.
