i would say mine is the upstairs bedrooms, i was always taught that bedrooms are private areas, so that sticked with me. besides we have a bathroom downstairs so there is no need for someone to go upstairs.

Not really. It's been a good year or so since I've had anyone over. Even when they did I didn't mind people being wherever. Unless it was a party, then I locked my room.

I'm not too fond of having people in my kitchen, but my apartment really isn't big enough to have a separate bedroom or anything.

Family: I don't like them being in my room without asking first or without knocking if I'm already in it. Obviously, I don't mind them just going in to put washed clothes on my bed or whatever, but if someone has been in my room and changed something about it it annoys me a bit that they didn't ask.

Friends: Other family members rooms, that would just be weird. Everywhere else is fine.

my room, and my office
