Sister A has her head screwed on so text her to babysit and offered pizza, she's happy to do so.
but then the usual happens...
She goes home and Mum sees it as an opportunity to see grandchildren so she insists on joining, so strict times are now wanted for leaving/ coming home (9pm) (sister A doesn't care and as we're taking 3 month baby with us it can be unpredictable, plan is to go when she sleeps and have her in carrycot). Bloody bet baby will settle 40min before Mum wants to leave! And Mum dictates she drives all, despite my sister being willing and able to travel alone...
Then Mum tells sister B (head not screwed on: in addition to lack of common sense unpredictable MH and previous incidents with dc in danger) who wants to come.
So Mum says it's unfair if they all come without sister C (who is a mess maker of highest order)
ARGH
So now my meal out will involve major fridge raiding, mess/cups etc to tidy and hyper toddler when getting home and strict hours to adhere to. Sister A is reasonable but gets pressured by the rest who inquire where she's off too.
AIBU to cancel meal? They'll be annoyed but I'm fed up. It's all 'it's not fair' from my mum every time you try to have just one round rather than an invasion force, I'll have them all round at times. Add in my Dad and two brothers and my small house and every visit is mayhem.
It's like never growing up when it comes to them! I could have written something in this vein 15-20 years ago only with a location change.
