An empty boat
will volunteer for anything.
--Jim Harrison and Ted Kooser,
from their collection Braided Creek.
Of course, one can appreciate the literal quality, the image of an actual boat just waiting, that call to adventure, or one can move metaphorically, the sense of the self as an empty vessel just available, that potential call to misadventure. Or both.
(I love that small book: Braided Creek.)
