This week, Sophie talks to Anne Welsh - author, librarian, and expert in cataloguing. Join Sophie and her guest in discussing the emotional energy associated with holding grudges, ‘caveats for continued friendships’, a whole new multi-faceted grudge-classification system, and the dangers of leaving your egg mayo sandwich in a library.

Sophie's new book HOW TO HOLD A GRUDGE: THE POWER OF GRUDGES TO TRANSFORM YOUR LIFE is available now in hardback, eBook and audiobook. Buy now http://smarturl.it/GrudgePodcast

The How to Hold a Grudge theme was provided by Annette Armitage, a composer, musician and teacher, and co-writer (with Sophie) of two mystery themed musicals: THE GENERALIST - A MURDER MYSTERY MUSICAL and WORK EXPERIENCE - A MUSICAL LOCKED ROOM MYSTERY.
