Re: "Keep it on."
I was worried that prudery and Puritanism was dying out but I guess I have nothing to worry about. I’m in complete agreement with Lisi Tesher regarding hygiene, but there we part ways.
You shouldn’t feel pressured to expose yourself if it makes you uncomfortable and you don’t need to lend any items to the mooching exhibitionist but don’t impose your dress code on others.
If the sight offends you, avert your eyes. Or, shower at home.
