Simon is looking forward to lunch with Patrick Mulligan, the first man he slept with nearly twenty years previously, while playing Puck in a school production. It soon becomes apparent that Patrick is expecting to see not Simon, but the boy who played Lysander, and their lunch is cut short. When Simon is approached by Patrick's wife the situation becomes increasingly tortured and darkly comic.
