opening like a mouth

   

who were those rocks you threw
into the water he asks what were
their names she says nobody and
he is silent he wants to tell her
that he threw a rock named
nobody in the river a few days
ago but it's not the same she
knows a different nobody she has
a different pile of rocks and none
of the names matter any more just
the perfect arc the entry the light
of the moon the path it makes on
the water reaching out to meet
her as she falls.
