Three years ago, when Zeitgeist Stage Company produced Alan Ayckbourn’s “Private Fears in Public Places,’’ numerous theatergoers — especially British expatriates — told artistic director David J. Miller they were pleased to see a company focusing on a later work by Ayckbourn rather than one of his oft-staged early comedies.

Since then, Miller has made sure that each Zeitgeist season includes an Ayckbourn play: “My Wonderful Day’’ in 2011, “Time of My Life’’ last year, and, starting Friday, “Life of Riley.’’
