Last weekend, my family had a wonderful meal at Casa de Fruta, an RV resort, motel, candy shop, wine store, gas station, and restaurant in the Pacheco Valley of Northern California. There is also an operational scale model train for the kiddos to ride. The terrific painting at right hangs in the restaurant. I posted it to my Instagram feed and included the full caption of the plaque above it: "Eugene A. Zanger, co-owner of Casa de Fruita, flipped over 3 million cups 1969-1999. Appeared on David Letterman Show 12/23/87. Enjoying retirement." Above is video of Mr. Zanger's appearance on Letterman.
Probably the best bit of advice Congresswoman Capito had was to offer up a distraction when things get too tense. "It may be the perfect time to bring in dessert, she says, or to announce that someone should take the family dog out for a walk."
My suggestion: Combine Capito's awkward segue with Wiseman's awesome tricks. Not only will you actually get your family focused on a new topic, they might even be delighted enough that they decide to ignore the fact that you just passive-aggressived them out of a heated debate. Happy holidays!
