Reminds me of the hen do debacle of a younger extended family member.
She had a massive hen weekend piss-up with all her friends (where apparently she ended up drunkenly crying her eyes out at midnight because of some perceived slight). No-one over 29 was invited or allowed. All the older relatives / friends breathed a sigh of relief tbh.
Then her sister organised her 'hen party', as though the other one had never happened, announced via text. An evening out in a lovely historic pub in a nice part of town (think Albert Dock). All nans, mums, aunties, older cousins, steps invited. Except a secret WhatsApp group sprang up which decided that all the younger friends were also going to go, were going to change the venue and turn it into a pub crawl, change the meeting time from 6pm to 8pm, and not tell the old farts they were doing this.
So the 'old farts' found this out last minute and sent their apologies on the day and didn't go.
The hen ended up drunkenly crying her eyes out (again) at midnight, and blocked loads of 'old farts' on social media, but not before she'd uninvited loads of these women to her wedding, many of whom actually ended up not going (and their male partners didn't go either).
The groom is one lucky fella.
