Not wanting to wait to grow up again, Jeff clicked on his age and changed it from 8 to 16. He was about to execute the change when an idea hit him.
"Wait! Of course!" he said. "It keeps mixing up the changes. If I try to get older, it makes me younger. I just have to do the opposite."
He changed his age down to 4 years old. Just before he executed the change, he hesitated, worried that Chronivac might actually function correctly this time.
"This had better work," he said. "Being 4 would be even worse than being 8." He heard footsteps coming toward his room. Jamie must be back with her screwdriver, he thought. "Well, no time to wait. Here goes nothing." He executed the change.
