Certain fall evenings

Corrosive obsession
ate its slow way in
as I grieved
the loss of your love
then ate its way out
along the same
scarred path
as I grieved
the loss of the loss.
All that remains
now I'm at rest
is this single
fading mark
on my chest
and a faint
lingering odour
of bitterroot
at dewfall
on certain
fall evenings.
