My sister has appendages connected to her ankles. They feature toes and arches, but I cannot call them feet. In color they resemble the leathery paws of great apes, but in texture they are closer to hooves. In order to maintain her balance, she'll periodically clear the bottoms of debris--a bottle cap, bits of broken glass, a chicken bone--but within moments she'll have stepped on something else and begun the process all over again. It's what happens when you sell both your broom and your vacuum cleaner.
