The region was in a drought.
Suddenly, rain splattered on the pavement; a dark storm cloud rolled and dropped from the sky, forming into a large gray dog with protruding tongue, happy eyes, and a wet, wagging tail. Children danced gaily around the dog.
Someone, a grownup perhaps, decided to capture it, thereby keeping the rain all to herself.
She fixed a chain about the beast’s neck and tightened it to secure her prey. The dog quickly dematerialized, leaving only a moist spot where he had stood. The sun broke from behind the dissipating thunderheads.
The rain refused to fall again.
