Shower while you can. Shave your legs for the days ahead. Run to the library under thick-falling flakes and obtain your finest haul, a medley of things, because when the electric sizzles out, you'll want an entity without batteries. Hug the Internet close for as long as you can. Vacuum your room, do your laundry, clean your sheets like a guest might be slipping into them tonight, a guest called windchill and cracked shingles.
