Ah, the house party – an oasis in the hot desert of gas stations, motels, and quasi-public drinking outside venues. They're a treat, and a rare one at that, until they're not. Until they go horribly wrong, or you go horribly wrong, or someone else decides to go horribly wrong on your behalf. You never know what to expect when you walk into a room full of strangers in some city somewhere in the night. It's a roll of the dice, and we've rolled it many a time.
