“Recognitions” by W.S. Merwin

Stories come to us like new senses

a wave and an ash tree were sisters
they had been separated since they were children
but they went on believing in each other
though each was sure that the other must be lost
they cherished traits of themselves that they thought of
as family resemblances features they held in common
the sheen of the wave fluttered in remembrance
of the undersides of the leaves of the ash tree
in summer air and the limbs of the ash tree
recalled the wave as the breeze lifted it
and they wrote to each other every day
without knowing where to send the letters
some of which have come to light only now
revealing in their old but familiar language
a view of the world we could not have guessed at

but that we always wanted to believe
