I share a flat with my friend's brother. Nice chap, we don't see each other often but he's tidy and polite. He has a girlfriend who often stays over. I don't mind that, but we have one bathroom and she regularly spends over an hour an evening in it during prime going-to-bed time. I have been waiting to wash my face and brush my teeth since ten. I'm exhausted and want to go to bed. On top of that I have a dodgy tummy and have been clenching my arse cheeks the whole time.
AIBU to bash on the door and tell her to get out? It's that or getting properly dressed and going to the supermarket down the road.
