Have you ever battled a spouse who is trying to stop global warming by turning the thermostat down to an “arctic wasteland” setting? Or sent a child to sleepover camp without a single pair of underwear decent enough to get hit by a car in? If you find yourself talking to your GPS, trying to shoulder-shimmy in Zumba class, or praying that you can get through another Thanksgiving without a repeat of the legendary Salmonella Bird of 1997, you know what it’s like to be carrying “The Mother Load.” A collection of the most popular humor columns that Nancy Crochiere wrote for The Daily News of Newburyport, Massachusetts, over a 15-year period, The Mother Load is a hysterical look at family life in the 21st century.
