The morning sun is so pale I could be looking at a ghost in the shape of a window a tall, rectangular spirit peering down at me now in my bed, about to demand that I avenge the murder of my father. But this light is only the first line in the five-act play of this day— the only day in existence— or the opening chord of its long song, or think of what is permeating these thin bedroom curtains as the beginning of a lecture I must listen to until dark, a curious student in a V-neck sweater, angled into the wooden chair of his life, ready with notebook and a chewed-up pencil, quiet as a goldfish in winter, serious as a compass at sea, eager to absorb whatever lesson this damp, overcast Tuesday has to teach me, here in the spacious classroom of the world with its long walls of glass, its heavy, low-hung ceiling.
