The article recounts the author's experience in junior high school, where they and their friends discovered the Command Prompt command 'net send' and used it to send messages to each other on the school network. They soon found out about the wildcard support of 'net send' and used it to send a message to every computer on the network, which led to them getting in trouble. The author reflects on the incident and how it was a harmless prank, but also a learning experience. The school's IT department eventually disabled 'net send' across the network.
