I once replaced every part of me
With robust designs that shined from within
Strong, efficient, I could run forever,
I had everything I needed, built-in.

I had nothing to be changed or improved,
I was a perpetual motion machine
With no ties to an inferior past
Cast away from memory, as though unseen.

Yet sometimes, in the shadow of the day,
When I feel a distant ache long denied,
Forgotten wounds of what used to be,
I wonder who I really am, inside.
