Sitting across the Thanksgiving table from certain family members might be particularly tricky this year, post-election. This hour, we’ll talk about maintaining common courtesy even when we disagree with people – and we’ll make sure we’re squared away with which side of the plate to place the knife and fork. We’ll be joined by Jeremiah Tower, author of “Table Manners: How to Behave in the Modern World and Why Bother” (Farrar, Straus and Giroux).
