In this slumber party style episode, Tilly and Abigail get real relaxed and chat about the things their families do to rev up for the advent season. Why does Christmas get more stale every year for some, and better and better for others? Also, is Abigail going to sing her original Christmas hymn next episode? Does she need a pie cart? Also, why does Tilly's son sit and stare at a train for half hour stretches, and what is a 48-hr shower?
