...go about politely telling one's MIL that she really shouldn't wash one's dishes?
MIL comes over to watch DSs while I'm at bar exam classes. She uses my food and dishes to prepare meals for herself. Not at all a problem. But then she 'washes' them. And leaves food on them. Ew. Gross.
It's as much a petty b*tch as a quest for advice, so I thought I'd put it here.
