The Curious Case of Phone Stacking: A Modern Social Ritual

In restaurants across the globe, a peculiar phenomenon has emerged in recent years. Friends gather around tables and, before settling into conversation, perform an almost ceremonial act: they stack their phones in the center of the table, creating a small tower of technology deliberately set aside. The Birth of a Digital Detox Ritual This practice didn't appear in etiquette books or social manuals. It evolved organically as a response to a uniquely modern problem—our growing inability to focus on those physically present when digital distractions constantly beckon. "I first noticed it happening around 2015," says Dr. Sherry Turkle, author of "Reclaiming Conversation: The Power of Talk in a Digital Age."
