The PPP makes everyone wipe down the hand basin (and the shower) after every use. She inspects the bathroom after you've used it, and there's hell to pay if there's a stray drop of water. Apparently wetness damages porcelain and taps. Who knew that!
So I've gone on a shower strike, as a protest and to avoid conflict over wiping down the walls after a shower.
I won't bore you with my aunt's rules about using the toilet, but you can imagine why my uncle used to pee in the garden. And why I choose to pee in the sink.
In the kitchen, the dishwasher is such a high-ranking device that she washes each dish by hand before loading it, to avoid dirtying the washer.
I too was raised with the Bavarian over-respect for machines. When I was young, even just lowering the gramophone needle onto a record used to bring me out in a sweat. Fortunately I was cured via a combination of :
• home DIY, where you learn to whack things, and even if something breaks you can repair it
• grope therapy, where you learn how to look dispassionately at your hangups, and re-program them.
