Eternally Fretful Desk Mate

You and your desk mate have never seen eye to eye, but that's largely because they're always finding something to complain about. Whether it's the temperature in the office or the quality of the coffee, they never seem to run out of petty annoyances. This morning, you had enough of their chronic grumbling and argued, only to end up in a bizarre room with a 'Make up or never leave' sign on the door. It's going to be a long, maybe endless, day.
