A Michigan woman was recently discovered to have been living inside the peaked rooftop sign of a Family Fare supermarket in the town of Midland, having built herself a cozy, furnished apartment complete with a little desk, houseplant, computer, printer, Keurig coffeemaker, and a cubbyhole full of food in the empty space within that kind of triangular roof structure common to large chain grocery stores, MLive.com reports on the woman employees have dubbed “the Roof Ninja.”
