This episode may hurt your head and cause you to think about things you've never thought about. How do phone sounds work? Are we relocating to Mars? How do traffic lights know when to change at night? For a bit of an easier listen, you'll also get to hear all about the latest addition to the Kelly family. Charleen and Ellie answer your dilemmas in Secrets From The Stalls - including how to deal with phone-addicted friends (and loud eaters!) in social situations, and should you worry that your ex is now in a relationship with a friend that he had throughout your relationship?
