Time is considered the fourth dimension. A force of nature. It is also interwoven with the fabric of space, warped and wobbled by the gravity of heavy celestial objects.
Loss makes us acutely aware of the passage of time, the weight of it like water pouring over us and carrying us away.
The last time I saw my father is at a fixed point in spacetime. That moment hangs suspended, immovable, immutable, and a part of me with it. We have sped away from that point at 130 miles per second for 18 years.
We are now 73794240000 miles from the last I love you. The Milky Way flung from the singularity, inexplicably, irrevocably.
Loss leaves us separated not only by time but an unfathomable distance. My grief, our grief is the long walk back.
