It only took a single glance across a restaurant for me to feel completely certain I understood someone else’s life. The evening had been ordinary—soft music, warm lighting, the quiet clatter of dishes—until I noticed Sarah, my neighbor’s wife, seated in a corner booth with another man. They leaned close, laughing in that effortless way people do when they feel safe and familiar.
