As a little girl in what is now North Korea, my mother, Bock Sill, watched as the communist regime dragged away her grandmother to kill her. In the horror, she found strength. She relied on that strength as she fled to South Korea during the Korean War. She used that strength to find a job, meet my father, Tae Hun, and immigrate to the United States to provide a better life for her children. Today, she relies on that strength to care for my father, who has Alzheimer’s disease.
