Poem of the Week: Lake Shore in Half Light

There is a question I want to ask
and I can’t remember it
I keep trying to
I know it is the same question
it has always been
in fact I seem to know
almost everything about it
all that reminds me of it
leading me to the lake shore
at daybreak or twilight
and to whatever is standing
next to the question
as a body stands next to its shadow
but the question is not a shadow
if I knew who discovered
zero I might ask
what there was before
