Ly Rithy is at home in the cheerful company of her granddaughters, 7-year-old Tiya and 12-year-old Srey Pin. Nestled away from the high-energy hum of the main avenues of the Toul Sangke neighborhood in Phnom Penh, Cambodia, Rithy’s home is found at the close of a quiet lane. Rithy laughs easily alongside her granddaughters as she hangs up clean laundry on a line, her dark red hair smoothed back into a ponytail.
