Sour Grapes (1921)
by
William Carlos Williams

The Poor

By constantly tormenting them
with reminders of the lice in
their children's hair, the
School Physician first
brought their hatred down on him.
But by this familiarity
they grew used to him, and so,
at last,
took him for their friend and adviser.
