They would come to our meetings prepared with these intricate exploits on encryption systems, worked out from front to back in full detail.\u00a0They would take over at the board, explaining their findings to me.\u00a0When I got lost, they would show me the way. It\u2019s the best thing you could ever experience as a teacher.
