Doors swell and tighten in winter and keep the secrets of houses to themselves beneath the intermittent cries of solitary owls. In spring, doors shrink and swing open on breezy sun-filled days, to let out the cramped spirits of airless rooms. Long delayed projects are continued or occasionally completed, still others are begun with an enthusiasm that will not stay the course. Man is a maker and must be doing, home improvements seldom lead to divorce.
