18th birthday party

[Frustratedandpissedoff]

My cousin has her 18th birthday party coming up next month. Her mum, who spoils her rotten and does everything for her, asked her what she wants to do in terms of party. My cousin said that she would like a house party with 30 friends. Their house is big enough to accommodate this, but my aunt is having surgery the week beforehand and will be unable to host. She looked into renting a venue for the party with a DJ, but my cousin insisted she wants it at the house.
My aunt and her husband and son intend to clear off for the night and let her get on with it herself. I said that my cousin will have to clear up after the party, to which my aunt laughed. I asked her what will she do if she comes home to a shit tip? She more or less said that she and he husband will clean up.
My aunt is caring for her dad following her mum's unexpected death as well. AIBU to think that this is princess behaviour on my cousin's part?

I think it’s probably up to them, isn’t it? It’s not like they’re asking you to help.

Personally I think handing over their home to an 18 year old and 30 of her friends to hold a party is absolutely crazy.

But. It's their house, their dd, their decision.

She's their daughter. They have taught her how she can treat them. They don't seem to have a problem with it so let them get on with it. None of your business.

I mean, I went to loads of similar parties way back when. I think it’s a one night only (also none of your business) they can deal with the aftermath. There will be an aftermath!

It’s not got anything to do with you.

myabe the tidying us is part of her present

I mean, it’s not really anything to do with you is it? If her mum won’t ask her to tidy up after, and has told you that her and her husband will do the cleaning, then that’s that isn’t it? You can always volunteer to go and help?

You sound jealous of their set up, but that isn’t your cousins fault.
