Susan Poulin and Gordon Carlisle are a husband and wife team, and the co-creators of “Spousal Deafness and Other Bones of Contention.” It’s a humorous look at marital life, and draws upon material from their own marriage. They’ve found that couples can relate to their production, and that sometimes a sense of humor and a little understanding are what every marriage needs. “Spousal Deafness an Other Bones of Contention” appears Friday, May 18th at the Concord City Auditorium.
