I always think: Man, it would be fun to be invited to one of these. Then I think: Wait... what if it's all weird... with cloaks and masks... like that one Tom Cruise movie? But in the movie, there was also a massive orgy, so I figure a mask and slight creepiness is not a bad price for mega-orgy.
But then I worry I'll see an ex there and she'll be all, "Figured you be here" and I'd be all, "Psh... I take it you're part of catering?" We verbally abuse each other for another 3 hours, all while drinking alcoholic beverages... which eventually leads to angry, ex-lover sex.
