Strong. Perhaps a knot of muscle or a face to wear. Or the bartender's hand slipped.
Fragile. Maybe a shattered glass orb or a note about to break. Or our egos.
Dark. Like Edgar Allen Poe or the center of a black hole. Or 5:00 in winter.
Light. "Let there be" or something that perforates the night. Or just the pillows, shedding feathers through tiny linen holes that float down near the heating vent then explode upward in the gust.
