It was graduation day. The chance to meet the students and their families, watching them turn for a moment from the adults who’d been in class to someone’s son or daughter, uncomfortably introducing “my parents”. They recognised their teacher in the crowd. Stopped for a selfie. Maybe he had made a difference, His particular peculiarities and personality, a character in their early career. Graduation was a moment they could remember those moments, those relationships. Every year, new classes, new relationships. Maybe some would remember him, he thought. The ‘retired’ teacher at the back of the hall watched his timeless avatar.
