Well, even for the times that I know EXACTLY what are you doing (e.g. because I saw you gulp down 10 big Macs and a box of laxatives before rushing to the bathroom) you still want privacy.
I'm not sure that's true. You might think you know what I'm doing in the bathroom. I don't think privacy and secrecy are truly separate things.
