Ah, the long goodbye. Essentially any time one person is forced to interact with another person this bizarre exercise in human interaction can happen. It’s probably happened to you. And it’s the dirt worst.
Imagine. Or recall. You’re at a party, family gathering, meeting, wedding, funeral, work function, bris, intervention, or something as low key as a few quiet beers with a friend… At some point you will invariably decide that the event or whatever is over, you’ve had enough, and you’re going to leave.
