Host Meg Wolitzer presents two humorous stories about marriages not made in heaven.  In James Thurber’s classic “The Breaking Up of the Winships,” a long-married couple fall out over Donald Duck. The reader is Kristine Nielsen. And in Louise Erdrich’s “The Big Cat,” read by Keir Dullea, two powerful wives, a bemused husband, and a symphony of bone-jarring snores.   The program also features an interview with Erdrich.
