A routine that never changes can get old. So this week on Selected Shorts, host Meg Wolitzer presents three stories that shake up domestic life, teaching the characters something new about themselves and their circumstances. In “Scaffolding Man,” by Jenny Allen, performed by Patricia Kalember, a woman in a drab marriage is intrigued by a “hot” stranger. In "Myrna's Dad," by Cyn Vargas, a father’s changing occupations hide a family secret. The reader is Krystina Alabado. And in “Overtime,” by Hilma Wolitzer (Meg’s mom), read by Becky Ann Baker, a happy couple gets a jolt when the man’s ex moves into their apartment. After the story, Meg interviews Hilma about what gave her the idea and her writing in general.
