" Inside the maize mill, the owners no longer had any use for a broom. The hungry people kept the floors cleaner than a wet mop. At the beginning of the month, the mill was packed full of those waiting for fallen scraps. The crowd would part long enough to allow women to pass with their pails of grain. As the machine rumbled and spit a white cloud of flour into the pails, the multitude of old people, women, and children watched intently with eyes dancing like butterflies. Once the pail was pulled away, they themselves on hands and knees and scooped the floor clean. Afterward, old women would rattle their walking sticks up inside the grinder as if ringing a bell, collecting the loose flour that drifted to the floor. "
