The Lessoning of You Knew Who

So little of you, you now knowing down
Life teaching you smaller bits of self
A growing descent
Certainty slides into mystery
Not doubt, mind you
But a searching more for what it was
We once comprehended of us
That time shaves away
Slivers us as the universe expands
Our search for exponential growth toward nothing
Riding a swerve that that will miss infinite understanding
Curved explorers of bullseye mind and target heart
Erase each note of the decomposing opus
Decrescendo of music dissipation 
Dimming light the path to darkness
Words eaten up in fits and starts
Pens broadsided letter opener gaps 
Eyes blinking back at blanker walls
Best guesses missing far more marks
A younger older stranger shoulders slumping
Shrugs of misremembering
Who you once were sure you’d been
