A lot of us run away from tough conversations. Anna Sale runs toward them. For nearly a decade, as the host of the podcast “Death, Sex & Money,” she has been having searching conversations about “the things we think about a lot and need to talk about more.” Now, in her new book, “Let’s Talk About Hard Things,” she blends reportage and memoir to reveal how speaking openly (and listening attentively) can fortify our relationships. That may sound simple, but as one of the book’s reviewers observed, “As vaccinated people begin to have joyous reunions with friends and family, after a year of isolation and Zooms, many of us are realizing that we’ve forgotten how to talk about the easy things, let alone the hard ones.” In this conversation, Anna — with her trademark warmth, curiosity, and candor — reminds us how to have those difficult conversations.
