My parents always taught me to remember that I have a lot to be thankful for. And it’s true, of course. I have all the food, clothing, convenience, and entertainment I could rationally desire. Friends and family. Tasks to do. Inane computer games. And, of course, the best things in life are free … new moons, summer breezes, sunshine on a rainy day, raindrops on roses, whiskers on kittens, and all that jazz.
