A Brief Meditation On Time - Drabble

Time gathered and heaped behind glass. Gravity was pressing down on the pile, driving the future  through the tapered present. Tiny grains of now. I try and clinch one in my sight, but it is too swift. Rapidly  supplanted  by another impelled from above. And then another. I can’t fix on any of these fleeting instants as they drop on to the mound of the past beneath. Whereupon they become swallowed and buried and I spend a lifetime trying to disinter any one lost moment. The future chamber is empty. Inverting  the hourglass I recommence the ungraspable passage of time.
