We host my in-laws at least once a month for Sunday lunch and they pop round at various other points in the month.
Almost without fail, FIL will use the loo and it will be left in a disgusting state after - stinking as he hasn’t sprayed, water over the floor from where he hasn’t dried his hands properly and items such as the soap put back in the wrong place.
DH knows this greatly annoys me but won’t say anything - ‘oh, he’s stuck in his ways’ or ‘it’s only once a month’.
I’ve had enough quite frankly, and feel like it’s getting to ultimatum time.
