I asked my grandfather for twenty dollars. "Twenty dollars?!" he said. "For what?" "To buy groceries," I told him. "When Iwas a boy,“ my grandfather said. “My mama would give me one dollar, just one dollar, and I’d go to the store and come home with two loaves of bread, two sacks of potatoes, a carton of eggs, th ree bottles of milk, a can of coffee and a box of tea." shrugged and paused. "Times have changed and ya can't do that now,“ he told me. "Too many security cameras."
