Mum is visiting since this lunchtime. So far she has taken it upon herself to do housework (I never ask and the house was clean to begin with), and so far has done the following:
Used a dirty tea towel (that was on the floor!) to dry washed dishes
Cleaned out the litter tray and then prepared lunch without washing hands
Took out the rubbish, came back and didn't wash hands
Lifted the entire kitchen bin lid off and rested it on top of the clean dish rack
She does stuff like this every time she visits and whenever I politely ask her to wash her hands or 'please, could you try not to do that' she either says I'm being silly or hysterical and that a tea towel from the floor is perfectly fine to be used and 'does it really matter where the bin lid goes.' When I point out I also have a shitty immune system she says 'oh yes, I suppose so.'
She also guilts me sometimes as in, 'well, if I'm doing it Wrong then maybe I won't do it, I'm only doing you a favour' GOOD don't do it, I never asked!
AIBU to go to another room and scream into a pillow?
