Another parable of the sower
Once upon a time a sower went out to sow. And as he sowed, some seeds fell along the path, and the birds came along and devoured them. So he put his seed pouch down and spent the next hour or so stringing aluminum foil all around his field. He put up a fake owl he ordered from a garden catalog and, as an afterthought, he hung a couple of traps for the Japanese beetles.
