Note: This episode contains discussions of murder and grief. Listener discretion is advised between 6:30 and 12:00 of this episode. You can read more about Sam Woll, a close friend of Zak’s family, here. On this episode: Jamilah Lemieux, Elizabeth Newcamp, and Zak Rosen help a listener who’s worried that her son’s play is skewing a little too much toward good guys, bad guys, and violence. What’s the difference between normal play and a red flag – and how can we make sure boys want to include girls? Zak found two great resources for this listener that we want to share: an article about violent play from Parents.com, and a book called Under Deadman's Skin: Discovering the Meaning of Children's Violent Play. We also go over our week in triumphs and fails — and then, if you’re sticking around for Slate Plus, we discuss an episode of RadioLab that got us thinking about how kids change our perception of time.
