take the man who knew everything:
he walked the boulevard knowing and thinking,
that a poorly-planted tree could, possibly,
let go its roots and knock him with a thump, or,
that he could perhaps, trip over a careless rock,
muddy his shoes in an unevaporated puddle
of yesterday’s rain, cross paths with ten thugs.
such foresight, he walked that boulevard with
a shield, thicker glasses, even thicker yellow boots,
except he could not stop no one ****, so,
he crossed the boulevard with that one discomfort.

now, take the man who knew nothing:
he walked the boulevard, and
crossed to the other side.
