Guest host Jane Curtin presents two stories about marriage.  In “Any Number of Little Old Ladies,” by Bruce Jay Friedman, a playwright uses his wife as a character and she’s not thrilled.  Blythe Danner and Maulik Pancholy read.   Another marriage is at risk in Roxanna Robinson’s “In Naples,” a trip that forces one woman to confront her feelings about her husband.  Betty Buckley performs this delicate story.
