The reason for privacy is not so that people will not know you go to the bathroom. It's to allow certain things to go on that you don't want other people to know about, when all is said and done. But the things I don't want other people to know about are not my sex life.

My family trained me to be polite to people I had just met, and that included strangers. You speak when you're spoken to. You look people in the eye when they address you and when you address them back.
