With growing amusement (and only mild alarm), my wife and I have been noticing how our parents’ quirks have gotten, well, quirkier. My mother and father, for instance, steadfastly refuse to text-message. “I don’t want to get charged,” my mother says. And besides, “Why do you need to text when you can just call me?” Of course, this assumes she hears her flip-phone at all—it’s often buried deep inside her handbag. She also has a habit of turning the phone off.
