Row

You know, of course
the depths plumbed
opened and turned inside
out by rhyme
to be widow perforce leads
to profound sorrow
a light skiff
blown about on sudden
seas             swells

        troughs
oars catch in dense waving
beds of weeds
but you must row
with some steadfastness
the point will be both
evident and elusive
floating on turbulence
hard enough to do
so
row
widow
row
