Sophomore year of college went with a friend to go hang out at his old college. We were supposed to crash with a few friends of his but we met a few ladies and ended up at a pool party. Next day went home and my friend started getting calls from one of his buddies moms asking if he'd seen him.
Turns out in the middle of the night a few guys broke into the house kidnapped my friends buddy and roomate. Took there car and drove them out to the middle if nowhere and executed them. I guess it was part of some gang initiation.
I was supposed to sleep there with my friend. I still sometimes think about it and get the shivers.
In very rare cases, irresponsible drinking has its advantages.
I got absolutely blackout drunk at an end of the year/graduation party and ended up having to get taken home early.
Later that night another student at the party ended up stabbing and killing 5 people. Turns out he had mental issues (schizophrenia) and thought everyone at the party was a werewolf/vampire who threatened his life.
He never went to jail but ended up being founded non criminally responsible instead...
