On New Year's Eve a few years back I was around 21/22 and my friends were anywhere between 20/25.

My best friend has a big house so he offered to host it there (as every year pretty much), so we all agreed to do dinner and party after.

We decided to go with barbecue, and we all brought a few things.

Without my knowledge, they are all pretty much gamers and also decided to bring their laptops and even towers to play during the whole day and night.

The result was me "alone" cooking with the dad of a female friend (whose wife died a few years back and offered to help since he would be pretty much alone or with some other family members, not sure).

Once we finished cooking and went on to calling them, no one came to eat because "they were finishing just one more game", and eventually the dad yelled at them and left, I just went eating by myself, and they all showed up a few minutes later looking like 5 year olds when dads scream at them.

I can pretty much say that was the weirdest thing ever, but they did learn because never again they did the same!
