Emergency vehicles have been heard all around here all day, so the theme du jour is sirens.
The ambulance speeds around the corner, siren blaring, tires screaming. The driver's eyes are locked on the cars before him, his thoughts on the hourglass spilling sand in his head.
Every call is the same for him - as soon as he gets his destination the hourglass is turned over and time starts ticking away. The only thing that ever changes is how much sand is inside and there's never any way of telling how much is there until it runs out.
And when the hourglass is emptied before he arrives, another light is extinguished, another mother, father, son or daughter is lost.
