Prudence is joined this week by Sorcha Reilly, an Oakland native preparing for her MBA, and who has been known to procrastinate by playing top 40 hits on the violin. Together they tackle letters about what to do when a board game colleague regularly drinks and crosses the line, how to handle a mother who uses guilt to stay involved in your life, how to explain your sudden surgical weight loss, and what to do when a nosey sister-in-law threatens to break a neighborly bond. Slate Plus members will hear Prudie and Sorcha discuss a letter writer who is wondering if they should report a co-worker who lies on her timesheets, and a groom-to-be who is getting pushback from friends and coworkers over his decision to take his fiancée’s name.
