Host Meg Wolitzer presents two stories in which some things are saved and some are left behind. In Haruki Murakami’s “Lederhosen,” performed by Aasif Mandvi, the traditional German shorts become a singular obsession for one half of a married couple. In Elizabeth McCracken’s “Robinson Crusoe at the Waterpark,” a couple and their son find themselves in over their heads. Mike Doyle is the reader.
