When this woman is wary of bringing her BIL to her new year's party, she asks Reddit:
For context, my family hosts a new years party every year, myself (22M) and my 3 siblings alternate every year for who hosts the party.
This year is my first year hosting, in a small-ish house that my girlfriend and I started renting at the start of this year.
Last year, my sister's husband Brad, who usually drinks pretty heavily at these sorts of things, got so drunk that he sh** himself before midnight and I had to spend my New years helping my sister clean up the apartment and bring her husband home.
Because of this incident, I decided that I didn't want him coming and ruining the party.
I still invited my sister, because as a family tradition I think it's unfair to allow her not to attend.
