The plight of the vanishing New England WASP is the subject matter of A. R. Gurney’s The Dining Room, running now at Sonoma Arts Live. No, it’s not a science lecture on the more annoying cousin of the honeybee, but a look at the cultural transformation of a specific component of 20th-century America: the White Anglo-Saxon Protestant.

Gurney, whose other works include Love Lettersand Sylvia, uses 18 vignettes and about 50 characters to chart the rise and decline of upper middle-class America. The scenes all occur in the titular location around a stately dining table. The table, once the center point of family life and special occasions, has been reduced over time to a place on which to fold laundry.

Wafting through the room over its two-hour running time are generations of unrelated characters, ages four to 90, all played by a company of six actors: Isabelle Grimm, Kit Grimm, Rhonda Guaraglia, Len Handeland, Trevor Hoffmann and Jill Wagoner. One actor goes from playing a stern, turn-of-the-century father lecturing his son on manners, to a young boy begging the family servant not to leave her job. Another goes from playing a real estate agent eager to make a sale, to a young girl pleading to go to the movies instead of dance lessons.

Scenes overlap with characters from one era occupying the space at the same time as characters from another era. There are no blackouts, as the action is continual and the actors simply glide in and out of the room. This led to some confusion with a few audience members, so much so that there were a few more empty seats post-intermission.

But it’s really not that confusing once you acclimate yourself to the style and buy into the premise of veteran performers playing children. The scenes range from the poignant to the humorous, with the most effective being a conversation between an ailing father and his son about funeral plans and a laugh-out-loud segment between an aunt and her nephew about a college photography project.

Director Joey Hoeber keeps his cast in check, and despite the range in characters, the show never veers into the cartoonish. If you don’t enter the theater expecting a traditional linear narrative, you’ll find yourself enjoying a well-acted, acute observation of a slice of bygone American life.
