I am a planner. I arrive hours early for flights, almost that early for doctor’s appointments and even —much to my child’s annoyance — movies. I inherited the “be prepared” gene from my father, a career military man. I have likened his approach to planning any vacation to creating a battle plan. There were always endless maps, brochures, schematics and graph paper (for packing) involved in every trip, well into the years when he was just planning a weekend getaway with my mother.
