This whole thing is kind of odd. I would lock my bedroom door for sure because I don’t want guest even to look in there. Perhaps it is messy and I didn’t have time to clean my apartment AND my not-being-used rooms. To turn around and say I am rude, paranoid or whatever is ridiculous in light of the fact that I just left you with my entire apart,ent including my keys! Maybe some of you have extensive cleaning help and don’t understand what it feels like to be embarrased by someone peeking into your room.
If I knew my guest was going to respond as you did, I would most certainly say no next time. If there is gratitude, you’ve disguised it well.
