Definition of a Jerk

This is a message
to the anonymous bicyclist
who bristled at being named a jerk
and then went on to diligently
prove that he wore the
descriptive with distinction
when he refused to give way
and permit two elderly
strollers along a forest path
to resume their blocked perambulation
preferring to have them stand
before him while he argued
unpersuasively that he most certainly
failed to fit the model of a jerk
because he had slowed down
considerately, he emphasized
and murmured excuse me
and his close passage did not warrant
being labelled a jerk even though
the one who credited him with
that soubriquet alerted his
companion seconds before 
she was likely to become a casualty
of an impending collision.
You are the sow's ear
that the term fits like a silk glove.
