Host Meg Wolitzer presents two works about being careful. The title says it all in George Saunders’ “Lars Farf, Excessively Fearful Father and Husband,” as the central character goes to greater and greater extremes to protect his family from—everything. The reader is BD Wong. And a couple tiptoe towards love in Lily King’s “Five Tuesdays in Winter,” read by Justin Kirk. A brief interview with King is included.
