A stranger at a shopping centre once caught my attention. She’d been speaking with a man, but interrupted him to talk to me. Quietly, kindly, she told me that my fly was not done up. Surprised and embarrassed, I laughed, thanked her, and pulled it up.
Months later, the moment came to mind when I was listening to a conversation about “the bystander effect”: our reluctance, when others are around, and we see someone needs help, to intervene.
