Many Waters, or: Novel

My smoothest rhymes and rhythm
Flow slickest with non-sense;
Cascading, facile cadences
Heart-searching swift dispense;
Thus jettisoned, adrift, my self
Flails many moments hence;
Still, tears masked by frivolity
Thin all these musings dense;
My sirens sing and wyverns fly,
Gnomes tap dance ‘top a fence;
Though cleverest of fantasies
Make laughable pretense,
As no amount of levity
Can offer recompense
For sundry wasted moments,
Which are my worst offense
