superstar -“Wait. I don’t understand the difference between a bathroom with a lock and a bedroom with a lock. Why the need for hiding under your blankets?”
That’s exactly my sentiments, without even locking any door. All the guys in Yeshiva think you must hide yourself under a robe or covers and they look at you like a Goy if you don’t. If people would bother looking up the Halacha it says you don’t have to cover yourself in a place where it is a customary to be undressed. It doesn’t say “bathroom”, Mikva, etc. I consider a bedroom the same way as the things I just mentioned. But unfortunately for you, I can only Pasken for myself – so good luck finding a Poisek that will Matter a bedroom for you.
