 The entire family (except for John) attends a Baptist church, of which Olivia and Grandma Esther are the most regular attendees.In the signature scene that closes almost every episode, the family house is enveloped in darkness, save for one, two or three lights in the upstairs bedroom windows.Through voice-overs, two or more characters make some brief comments related to that episode's events, and then bid each other goodnight, after which the lights go out.
