Here's an interesting article that offers interesting suggestions for Responding to Rudeness which should work well in a class in the discussion of conversation or a variety of other interpersonal topics. Among the suggestions offered are how to respond to catcalls, unwanted and negative comments on your appearance, or friends who reveal personal information. It would be interesting to see how students would deal with each of these several issues and if there's a gender or age difference in the responses.
I want to bring to your attention a new book by a friend of mine; we went to graduate school together at the U of I. The book—Lydia Pinkham: The Face that Launched a Thousand Ads by Sammy R. Danna (Rowman & Littlefield, 2015)--is about Lydia Pinkham, her vegetable compound (which is still being sold), and the revolution in marketing and advertising of which she was a major part. Congratulations Sam; you did a wonderful job!
