The person went feral. Back into a state of nature. It's the
hunter-gatherer Eden ruined by Western Civilization that we're told we

represents the nuts and berries. She grazed, and discarded the hulls
right where she stood, just like all our neolithic ancestors might.
Slept in a nest. Pooped in one spot. When finally challenged for
possession of her particular midden, located by the sylvan glade of
Pizza Hut and the 7-11, by a member of a more prominent tribe -- the
landlords -- she went off to make a nest somewhere else.
