A Crabby Day

I sit on a beach, a bit mellow and sad,
when out from a burrow, scuttles a crab.
The shelled critter stares, across the sand it zooms,
it hasn't seen anyone, beset by this gloom.
It is there for a moment, then fades out of sight,
The shelled critter has no input, on my weary plight.
When out from my sorrow, bemused and, glad?
I sit on the beach, an monument to a crab.

Happy Filthy Friday~.
