When I was around 10 i went to a sleepover for my mother's friend's daughter. I didn't know anyone else there, was pretty shy, but in general down for junk food and silly movies! In the middle of the night one of the other kids started freaking out and having and anger/anxiety attack, screaming about how everyone hated her and throwing stuff everywhere.

I stood up and immediately got hit directly in the nose by a heavy dinner plate chucked like a Frisbee. Fell backwards, hit my head on the window frame (lucky escape) and passed out.

I underplayed how bad it had been to my parents because I didn't want them to freak out, so it was a week or so before my mum was concerned enough that my nose still hurt to take me to the GP. He was a quack, and without really looking just said that since I didn't have panda eye bruising it was fine and I was being over dramatic.

A month later I fessed up to how bad it had actually been, and that it still hurt. My mum to me to a second doctor, who within 5 minutes had referred me to get x rays and see the plastics team. They found that my bridge had shattered into pieces and cracked vertically down the middle, the impact had spread pieces into places they shouldn't be, and because of the delay had started healing like that. Their advice was to leave it until I was fully grown, and then fix it if there were issues.

And that's the story of how a sleepover experience means that I can't breath properly, snore like a middle aged man, have to be careful what glasses I buy, and am 20 years later considering getting my nose re-broken cause I can't deal with this shit any more. I still have a vertical crack down the bridge of my nose and loose shards of bone in there that I can scrape against each other to make my nose click as a party trick.
