We’ve helped people apologize, confront their bullies and rebuild frayed relationships. We’ve revisited a disputed broken arm, a sorority drama and a suitcase of old love letters. Then, we go on a quest with them to try and make things right. In each episode, we take a moment from someone’s life that’s unresolved. The show, created by Gimlet Media, is hosted by Jonathan Goldstein, formerly of “This American Life” and “WireTap” on CBC Radio. This is something I think about a lot because I’m a producer for the podcast “ Heavyweight,” which is about exactly that. In this way, a single moment can pester us for years and years - unless we return to the past and confront it head on. Our poor choices and hurt feelings fade to the background, until another quiet moment beckons them to come pick at us again. But most days, we try to ignore these unwelcome memories, pushing them aside so we can buy groceries or go to work or do new things that we won’t regret. We obsess over these moments when we can’t sleep, or when we need a good cry. We all have moments from our past that gnaw at us - a regret, an unanswered question, an old tragedy.
