Simon was at his desk at home, working on the family finances, when suddenly...he blinked. "Oh, my god," he said. He'd been acting exactly like Johnny...John...his former father had. He'd wanted his father to know what it was like to be on the receiving end of things, but...he suddenly realized that meant he'd turned into the sort of father he hated. Adult Simon and Child Simon were at conflict. Child Simon didn't like what he'd become, and Adult Simon had an epiphany of his own.
He needed to fix this. But how? He logged back into the Chronovac program, and started to think. How could he fix this? Should he reverse it, adjust it, proceed with his original plan? He sat there for a long time, thinking over the possibilities, looking at the settings with the attention to detail adult Simon had, that his 12 year old self hadn't.
Finally, he started keying in instructions. He was also, fortunately, a better typer than his old self.
