A wise philosopher once said, \u201cSome things never change.\u201d You\u2019re probably thinking that was Plato or Aristotle or Hegel or Homer Simpson. No. It was my wife, and she doesn\u2019t even have a degree in philosophy. Some things never change, she said, while she was wandering around the house, picking up after our oldest daughter, who recently came home for the day. Fortunately, it was only one day although it seemed like a lifetime. As another great philosopher, Yogi Berra, once said, \u201cDeja vu all over again.\u201d She\u2019s living proof that some things never change \u2014 even though Buddha said \u201cEverything changes.\u201d She, like my other three daughters, has a mental condition of inexplicable origin. The NEVER finish their drinks, whether it\u2019s a bottle of Smartwater, a glass of Cabernet or a mucho grande Starbucks. Who can be so extravagant to waste a $6 latte? At holiday celebrations, our house is cluttered with unfinished drinks so I\u2019ve adopted a counter strategy. I plan to fill the Dasani bottles with tap water and save the leftover wine in their glasses for their next visit. They\u2019ve behaved like this since they were kids. I still remember emptying milk from their sippy cups down the drain, along with half-finished juice boxes and cans of Pepsi. But the wasteful behavior doesn\u2019t stop there. I also followed my daughter around the house, turning off lights. Whenever she enters a room, she turns on the light, and when she exits, the light stays on. At one point, every room on the second floor was illuminated \u2026 at 3 o\u2019clock in the afternoon. I\u2019d have more sympathy for this behavior if she worked for United Illuminating or Eversource and her annual bonus depended upon electricity consumption. When they were kids, I was constantly flipping off light switches. Decades later, I\u2019m still doing it. Then, there\u2019s the thermostat, which I\u2019ve decided to put under lock and key. Sandy and I went out, and when we returned, the house was hotter than South Florida in August. Our daughter had cranked the thermostat up to almost 80. Fortunately, our furnace doesn\u2019t run on nuclear power or we would have had a meltdown. Who goes into someone\u2019s house \u2014 even their parents\u2019 \u2014 and messes with the thermostat? That\u2019s like rummaging through someone\u2019s medicine cabinet or underwear drawer. What really frightens me is that my sons-in-law and the grandkids behave the same way. Half-finished drinks, wasted plates of food and profligate energy consumption. They have no sense of frugality. As my philosopher wife says, \u201cEasy come, easy go.\u201d This is proof of what was once notoriously called the \u201cgeneration gap.\u201d Our minds must be wired differently. I promised I wouldn\u2019t say this, but I can\u2019t control myself: \u201cWhen I was a kid\u2026\u201d When I was a kid, we had to eat everything on our plates, even liver and spinach, and believe me, it wasn\u2019t easy. If we didn\u2019t clean our plates, we couldn\u2019t get up from the dinner table. And we NEVER left unfinished glasses of juice or milk around the house. Bottled water hadn\u2019t been invented, and if it had been, my father would have prohibited it. \u201cDrink from the tap,\u201d he would have said. \u201cThat\u2019s why we pay the water company!\u201d If I left a light on in a room, he would drag me back there and tell me to turn it off because electricity costs money \u2026 so shut the front door, not to mention the refrigerator door. I was always told, \u201cYou don\u2019t live in a barn!\u201d And the only thing more sacred than his liquor cabinet was the thermostat, which only he was authorized to touch. My parents were members of the Greatest Generation, and they lived through the Great Depression. Many nights they went to bed hungry and many days they walked to the harbor to collect coal to heat their apartment. To the day that she died, my mother ignored expiration dates because she believed they were a conspiracy by the farmers and the grocery stores to get you to waste perfectly good food and buy more. Buddha was wrong. Some things never change. Of course, Buddha never had kids, although I\u2019m sure he enjoyed a glass of Cabernet now and then \u2026 and drank every drop.
