It seems like such a power move: "un-friending" or blocking someone on social media. It's the modern-day equivalent of someone on a 90s sitcom or daytime drama saying, "I'm outta here" before leaving an argument and walking out. Jeremy Bradley doesn't understand the politics of social media blocking when adults are communicating -- or not communicating. He recently discovered that several relatives "un-friended" him and laughed because he had no idea it happened. "Was it last week? Three years ago? I don't even know," he said. "Clearly it wasn't impactful to send a message." He talks about how juvenile and petty people make social media communications.
