Today, as I pulled the fresh, fitted sheet snug against the mattress, my eyes caught the knicks in the walnut headboard that has served as a pillow stop for generations of my family as far back as the 19th president, Rutherford B. Hayes. Even as my own fingernails brushed against the resilient wood, I reflected on how our lives today, as we celebrate our 46th president, are so drastically different from the lives of those who first pulled their sheets snug–27 U.S. presidents ago. So drastically different, yet so terribly, brilliantly similar. And familiar. Familiar like the cozy cradle of a pillow against a lovingly knicked headboard.
