For some obscure reason he finds it impossible to remember to flush the toilet. Or to lift the seat and wash his hands. It drives me nuts!
I know it's not for effort on my part. I spend a good part of my day re-directing him back to the bathroom to wipe the seat, flush the toilet and wash his hands. I'm like the toilet police.
Surely it should be like second nature by now? You do something enough you don't even think of doing it, it just happens. Muscle memory. I've driven home from the in-laws or sometimes and have no recollection of the actual journey. I could do it blindfolded.
So why, oh why, can't he flush the bloody toilet!?
