Context: I'm moving in with my partner in month. About 3/4 of my possessions are now at his as we take a car load every time we visit each other. He was at mine this weekend and his parents spend the weekend at his to do some walking and sightseeing (he lives in a scenic location and they tend to use his house when he's away to have a break from the city.) I have no issues with this. What I am pissed off about is in addition to the normal cleaning and hoovering his mum does (she can't help herself) it seems she had been through all my drawers and folded my clothes. Which on the one hand is a nice thing to do as they were all just shoved in there waiting to be sorted when I got time, but on the other hand seems a massive invasion of privacy. She will have seen all my lingerie etc as well as 'normal' clothes. I'm seriously unamused. AIBU?
