As the credits started to roll, everyone started to leave. Everyone, that is, except two particular cinema goers. Sitting a few rows apart, they made a concerted show of not leaving, albeit whilst also letting people pass. It was something they had come upon independently, somehow, the notion of staying put until the final words of the credits had scrolled past. They had very few actual reasons for it, yet they persisted. And, seeing as there were no post-credits scene this time around either, they too started to leave.
They nodded wordlessly at each other, acknowledging a peer among strangers, then walked on home.
