Full, luminous, silver moon casts a glow through the dark. Bright Venus hangs below. The Milky Way and the constellations counterpane the sky. A lamp shines in a window across the street where an old man keeps vigil at his wife’s bedside. And at the corner house, light shows through the curtains of the baby’s bedroom. The midlife insomniac, the elderly carer and the sleep-deprived new mother are all watched over. This too will pass.
