I wake to bright sunshine streaming in at the windows, and look out, it seems, on a vast snowfield, a white plain with rounded hillocks reflecting the brilliance of the light, extending to the furthest horizon.
A few minutes, and the snowfield is invisible. Everything outside is invisible but the dampness on the windows, and an all-pervading fog, shutting me, claustrophobic, inside.
Soon the fog too is gone, and now a steady drizzle beats on the glass. I have to leave the warmth inside, descend the steps to the grey gloom of an English morning.
But looking up, I know that the clouds that cover the sky, darken the earth, are mere vapour, and above them the sun still shines.
