She kept a stranger’s coat in her closet for 30 years. In the 1990s, a Korean schoolgirl in Japan was attacked in public, her traditional uniform slashed with a blade while bystanders walked past. A Japanese high school boy named Norihisa Koyama stopped, took off his brand-new winter coat, and wrapped it around her so she could get home safely. She never threw it away. For three decades, she held onto it with only his name stitched inside. This year, she saw that exact name in a newspaper article about a 50-year-old man running a charity for struggling single mothers. It was him. She finally tracked him down in Tokyo to return the coat and thank him in person. Never underestimate what one moment of courage can mean to someone for the rest of their life.
