I hate parties, personally. Not that I have been to one in ages, seriously, like 8 years. Not only that, but there's just no point in drinking, or getting drunk. My philosophy is, if you have to get drunk to enjoy yourself, you must be either a boring person, or totally incapable of letting loose without a little help from Jack, Jim, and a Turkey.
Bad experiences with alcohol swore me off of it. Night of the senior prom in 1997, I probably smoked a bowl or two, and decided it was a great idea to follow that up with a drinking contest. 10 mudslides shot glass (about 3 shots in one) Coke/Vodka, then 10 straight up Vodka after that. I won, but in the end, I lost.
I was drunk for 3 days straight. Not a hangover mind you, I was virtually incapable of moving, so I told my parents I had the flu. Thankfully, it was a 3 day weekend.
Best memory of that time? Owning my friends bathroom wall with literal projectile vomit. Worst memory. The entire night, and remembering how young and stupid I was.
