It was weird how McCafferty just showed up one day at a team meeting. There wasn’t a job posting, there weren’t any interviews. He just showed up one day and he had a badge and a laptop and a parking space. Human resources didn’t remember hiring him, and the boss didn’t remember anything. And he knew the company and the projects and all of our platforms and software and tools perfectly from day one. The next day, he was gone. No one remembered him ever having been there. It made me wonder about my own existence and I’d disappear suddenly.
