You asked Emily to be your plus-one at your uncle’s wedding because they were in the same spin class. Things are going pretty well–you kept a low profile in the service, chilled in the last pew and played hangman on the program. At the reception, you are assigned to the Random Single Friends table with some passable talent, and within the first ten minutes they roll out a nachos bar. Solid wedding. But the DJ starts off too strong with “Shout” by the Isley Brothers, and while you roll your eyes, Emily catapults onto the dance floor and launches into a full body twist/mashed potato. By herself. You have a choice: you can either leave out the back door or do the unthinkable and join her.
