Sand In My Shoes
Time is an abstract concept. Yet the seconds, minutes, and hours are woven into the very fabric of existence just as surely as the matter around us. The matter inside us, for that matter.
Forgive me the pun. It may be the last one I have time for.
Understanding time is an integral part of the universe doesn't make it any more concrete. Time depends on where the observer is located.
My days as a young man passed by so quickly. Now, I look down and there's nothing but sand in my shoes. One breath of wind, and I'm gone.
