Admiral is famousJonas was ten and mad about fish. He taught his goldfish, Admiral, to swim through a hoop, and filmed it. Dad said, "Let's set up the app together." Then Dad's work phone rang. "Back in two minutes," he said, and Jonas tapped Post. Whoosh! The counter said ten people had seen it, then forty, then a hundred, then a hundred and fifty. But Jonas had only twelve friends in the app. Dad did not shout. "The video is public, so anyone with the app can see it," he said. In the settings, the switch for who can see your posts was set to everyone. "Some apps start out wide open," said Dad. "It is just how it started, and nobody has to be in trouble." Jonas turned the dial down to friends. He took two names off the friends list because he did not know them. He set messages to friends only, comments to family, and turned off the switch that told people where the video was made. "Apps change," said Dad, "so every few months we will look again together."
