There is no difference between a male restroom and a monastery. Upon entering you have taken a vow of silence. You do not speak, you do not make sounds, you do not moan. You do not make eye contact. You must maintain 1 urinal space between other bathroom monks if possible. There is no physical contact. The male restroom is a holy and sacred place and its traditions must be upheld.
Don’t invade others personal space. I don’t want to be able to smell your breath. Or your body odor.
On a staircase, the person who’s going down the stairs should move out of the way of the person going up the stairs.
Always pass the slice of birthday cake on until everyone has a piece.
When you are a guest in my house, you can’t just look through my stuff!
