A few years ago, my sister decided to host xmas at her house for the first time ever. My sister who has never cooked for more than about six people before is now making Xmas dinner for 14 - all my family (so sisters and husbands and kids) and her MIL who is fairly witchy. MIL says she will bring starter of her choice.
A few days before, MIL says her even witchier sister is going to come too (these are both women in their 70s incidentally).
On the day, MIL turns up with the starter (which she chose). Quails eggs, uncooked so in the middle of trying to prepare food for 5,000 we have to find a pan and a ring to cook the eggs. And then my sister go 'What do you mean you don't have any celery salt?' She also brought a side of smoked salmon, unsliced. She forced my BIL to slice it and then stood behind him the whole time shrieking 'no, no, that's nowhere near thin enough!'
Witchy sister did absolutely sod all. Didn't bring anything, didn't help, just sat there, pursed lipped. Referred to my niece as 'that girl' as in 'get that girl to fill your glass up'. And complained about the food. Loudly 'These bloody carrots are awful!' 'God knows why anyone bothers with turkey, dry as old boots'
So that was the last time they were invited. How about you?
