I never take naps. Not because I don’t become sleepy on a lazy Sunday afternoon or a sultry weekday evening, but because upon waking from my naps I feel awful and ornery and not particularly happy about being alive. And then there is the problem of sleeping at night after napping during the day. I know people who take daily 20-minute “power naps” and wake up happy and refreshed, full of vim. Not me. But for Mom and Dad, naps have become necessary and pleasurable parts of the daily routine. At their age, the mere act of living is fatiguing, requiring rejuvenating naps. And after Dad mows the lawn or Mom finishes the laundry, they are ready to settle drowsily into their recliners, where sleep overtakes them. They awake cheerful and ready for the next round of life.
