Bathrooms...open door policy?

If I'm alone, door is always open because my apartment wont judge me, ha. If family is over, door is open for a quick pee because we're probably mid conversation. Of course, we politely avert the gaze, but it doesn't stop the dialogue. If friends are over, closed outta respect for their sensibilities, because they may not have had the same upbringing. Don't want to offend unnecessarily!

As to the other- poop stinks. You don't want to marinade in your own smell, why would you want to afflict other people with it? Door closed, fan on, window open, air freshener if you have to (because in my opinion it just makes it worse)- and if possible, use the back bathroom, away from other folks.
