It's a matter of light... the tilt of the sun, the shadows stretching across the grass, the glow in the crashing waves, millions of tiny grains of sand sparkling. You can feel summer ticking by, a slow, gradual fade the daylight, getting slightly, oh, so slightly shorter. There is a glow in our faces and hands, a spark of light in our eyes, we know this isn't forever, the night descends, a blackness with a hint of light, luminous-luxury, the fading moments of another lost summer.
