I started using carry-out at the grocery store when I got pregnant. Even when I could still lift the bags, I decided not to. Having put off pregnancy until forty, I didn’t want to take any risks. After a month or two, Cao showed up. He looked Vietnamese, his black hair slicked back, new-employee shiny. At first I didn’t care who carried my groceries, but then I started lining up for the registers he worked. Cao made the extra effort. He frowned slightly as he dealt the items into sacks that were just heavy enough. He double-bagged without being told. And he smiled: a smile and a little nod to sort of bump it into place, then a shy look away, back to business.
