If you were to tell me a marriage could teeter on the brink of destruction simply due to the addition of a dog … I’d have countered that no one would let canine conflict get that far. Only that’s exactly what happens in the Playcrafters Barn Theatre's production of Sylvia, written by A.R. Gurney and directed by Kathy Graham. Friday’s performance ultimately left me feeling like I am killing it with marriage, as both my husband and I agree on our position on getting a dog: While they’re great, dog ownership simply isn’t for us.
