It's strange how family members growing up in the same household can be so different isn't it! It's a shame they put so much time and energy into negative emotions rather than figuring out what they're angry and frightened about. Definite nominees for room 101!I have a sister like that. She's dark, delusional, and nasty and lives behind a veil of self-righteousness she calls religion, but I can see right through it. I haven't spoken to her since our mother died in 2015 and I don't miss her one bit. I've 2 other sisters who aren't psychos. I've never been to my crazy sister's house (in South Carolina) and she has no idea where I live, which is perfectly OK with me.
But before the modcopter arrives on the topic of kitchen messing my friend who has a large place in France that likes to have friends come and stay has NO ENTRY signs on the kitchen doors and a plastic chain across the doorway to stop 'helpful' people interfering with the cooking!
They have a fridge and sideboard in the dining room for people to help themselves to drinks and snacks but STAY OUT OF THE KITCHEN! which I think is fair enough.
