This week on Pop Culture Happy Hour, NPR Monkey See’s Linda Holmes, Trey Graham, Glen Weldon and guest Barrie Hardymon talk about the evolution of public grief. From the newspaper obit to the tweet, how have remembrances changed? We also delve into the extra materials that are included in books that we either like or don’t like: epigraphs, acknowledgments, maps and more! All that, plus What’s Making Us Happy this week.
