To not let my son have a house party?

[MrsMuddlePluck]

Our living room is full of music kit & dining room full of ornaments & heirlooms. I'm fed up of hearing stories of kids throwing up on carpets & damaging furniture.

Aibu to say he can't have his 18th in the house?

We had many house parties growing up and nothing was damaged as our friends respected our property and vice versa.

I also knew a boy who tragically lost his life after being killed at a house party fight.

There are two opposite ends of the spectrum and they very much depend on the people who will be in your home. That being said, your home and your rules so no, you would not be unreasonable to say no.

Why can't he just hire a hall or something?

YANBU. He can have one somewhere else.

Not at all - the things that go on in house parties around here have put me right off - and that's mid-teens not 18 y/olds. That said, it does depend on what his friends are like.

YANBU. I let my DC have a party and it was truly awful.

What's wrong with a village hall? Or get rid of the ornaments

Isn't the pub the best place for an 18th.

Hire somewhere. Definitely!
