How do you tactfully let your sister know it’s time for deodorant? Or that you hate her dog? And how do you protect your sister from your overbearing parents? This week, Mallory Ortberg and guest Jasmine Guillory bring their advisory, legal, and child-of-therapists expertise to bear on the thorny questions of sisterhood, including a candid, live call with a listener (available only at Slate Plus!) Plus, Mallory reflects on being the Jack Johnson of road rage, responds to people who think it's just fine to give away your mom's dog, and spends a few minutes reveling in the newly-released footage of Jerry Lewis' long-lost Holocaust clown movie.
