I once met a beautiful East African girl named Mercy, a patient at a hospital where I volunteered in Kampala, Uganda. During one of my visits, the girl’s teenage brother summoned me to his sister’s bed. He explained that their parents had died and he, at age 14, was his sister’s sole caregiver. “I have learned you and a Mzungu man [my friend, David Kuo] gave pillows to the patients last week,” he said. “My sister, named Mercy, wasn’t here when you came. She has never slept on a pillow before. Would you please bring her one?”
