My best friend recently moved back from another country and lives round the corner from me. It's great to have her back, she's like a sister to me, etc. etc.
I'm going through a hard time at the moment and she has been great, popping in and spending time with me, making me tea etc.
However. She has recently started walking into my house without knocking. This is completely unannounced, no prior warning and she often just appears in my hallway, scaring the absolute shit out of me and OH. The cherry on the cake was yesterday when she text asking if I was awake from my nap and can she pop in. I hadn't had a second to reply, when I heard a noise and she appeared at my bedroom door. She must have snuck up the stairs because I didn't hear a thing until I saw her face. Safe to say I jumped out of my skin. I think what I found hard was that she just found this funny, and it almost felt like she didn't really care what I wanted. I had actually wanted to be alone.
I like to think I've got an open door policy, I tell people to drop by whenever they like, but to at least bloody knock on the door or ring the bell!
AIBU to lock my door even when I'm in? I really don't want to, but I can't bare the thought of having to talk to her about it, it just makes me cringe so much. Or is this a nice thing? Am I being over sensitive?
