Haha dutch guy here... Who cares? Our bedrooms have curtains! Actually living rooms usually as well, but we are reluctant in closing them I guess. Also, you'll often find patches of intransparant glass to prevent directly looking in.

But then the horror to go to the US and find toilets in i.e. hospitals that don't have doors closing all the way. You can literally stare someone in the eye through the crack in the door, or over the door, while he's taking a dump. Holy cow. Imagine the sounds echoing through the collective toilet room. My god. I'm still recovering from my visit to the prestigious Memorial Sloan Kettering Cancer Center. Having a s* together with someone in the next stall is a whole new level of intimacy I was not ready for.
