The Sleepy in your group is the one that goes out the least. She has a job with epic hours (think lawyer or marketing executive), and while you’ve known her forever, you’re more likely to have a Bigfoot sighting than to catch a glimpse of her. So when she RSVP’s last with a “well, maybe, let me see how things are at work," everyone is pleasantly surprised. More than two drinks is a rarity for Sleepy. If you can get her to the club, she’ll nurse her Ketel One and tonic for at least an hour (or two), happily volunteering to watch the purses while the rest of the ladies dance. Not wanting to be a party pooper, around 11pm you’ll find Sleepy sitting upright on a couch with her eyes completely closed. Is she napping? Is she resting? Is she wasted? You’re not sure. If you wake her, she’ll respond with a groggy, “I’m good. I’m good.” She wants to party with her girlfriends, but even Cinderella can stay out later than Sleepy.
