My bedroom had like... a plastic door thing that anyone and anything could walk through at any time; there was no privacy as you could NOT make the door stay closed. Also - my bedroom was used for daycare, so even at age 15 it still looked like I was 5 years old as my shelves were full of my old toys and daycare toys (the same was true for my brother's room.) So zero privacy. And the shower was in my parents bedroom and not in the bathroom (really small and old house), and it ALSO had one of those doors. My parents would walk it at any time while you were taking a shower to get something from their room - or little daycare kids would wander in, and who knows what. Even the actual bathroom - the only room with a door, had a latch-hook. That if someone else REALLY wanted in, they just needed a pen to unlatch it. I used to hide in there from my younger brother and lean against the door to keep him out. I forgot about doing that until just now actually. Probably why I value my privacy so much now.
