Wow, this has put some of my relatives / in-laws rules into perspective! I dread having to visit some of them...
Nothing but kettle out on kitchen counters - toaster and coffee machine to be put away after each use - extremely annoying! Counters are all granite, but coasters / trays have to be used at all times!
Everyone must be in the same room at the same time (exception of bathrooms obv). So no lie in, no watching tv / reading a book in between meals / whilst someone is cooking.
Windows closed at all times in summer, even if there is a heatwave (to stop flies coming in).
No milk down the sink (septic tank issue), so have to go to end of garden to empty baby bottles / porridge.
No red wine / coffee in living room (cream carpet).
Tablecloth to be used at all mealtimes (in case table scratched - they've had it years but suddenly super precious about it).
Must wait to be served breakfast, even if breastfeeding and starving, and don't really want to wait for pancakes and eggs and bacon, but just fancy a bowl of cereal. And must help with washing up of all milk jugs / small containers for jam and fruit dragged out for the occasion. Can't just pour milk straight from the bottle for a cup of tea?!
Probably more that I'm forgetting.
