Guest host Jane Curtin presents three stories in which small things count for a lot.  A discarded sock reminds one woman of her ex-husband in “The Sock” by Lydia Davis, read by Kaneza Schaal.  Sisters find a chess set at a department store in Meg Wolitzer’s “Deep Lie the Woods,” read by Blythe Danner.  And old-time jazz musicians and their funny clothes, food, and drink charm a young drummer in “Nightblooming,” by Kenneth Calhoun, read by Josh Charles.
