“The Niagara River” by Kay Ryan.

As though
the river were
a floor, we position
our table and chairs
upon it, eat, and
have conversation.
As it moves along,
we notice—as
calmly as though
dining room paintings
were being replaced—
the changing scenes
along the shore. We
do know, we do
know this is the
Niagara River, but
it is hard to remember
what that means.
