re: Delusional people who you know are doing coke and the things they say

I went to a NYE party last weekend that was about 10 close friends. One of them invited a girl over, who showed up with 4 other people who didn't know any of us, and 3 of them proceeded to go into the bathroom about 6 times in an hour to do coke. It was beyond trashy. Who does that at a small gathering of people that you don't know?
