"I know what the problem is." Jenny said. "You just can't let go and act as an 8 year old. You would have much more fun if you did"
"I guess that's true." Jeff shrugged. "Are you suggesting that we shouldn't use the Chronivac, and that I should just adapt?"
"Not exactly." Jenny gave a cheeky smile. "We'll use the Chronivac. Look. There's a ton of mental options. We'll make you think more like a kid. We won't remove your memories, just make you a little immature."
"Eh." Jeff was skeptical. "That sounds a little risky. What if I mess with Chronivac while I am, er, childish and reckless?
"Relax." Jenny assured him. "I'll be in control just in case. Like I can make it so only I can use the Chronivac. there's a ton of safeguards."
"I guess it's fine. We could try it." Jeff gave his okay. "but
Jenny immediately begun picking the options. Jeff would have the maturity he had when he was 8. He would still be aware and retain his memories, but he would not remember some things such as education past third grade. Nor would he remember the details of his sexual experiences.
"You said no memory changes." Jeff protested.
"Well, it will make it so class is more engaging for you, and also it avoids you blurting out a lot of stuff you shouldn't know. We can change it back unless you don't want to, I mean you're the one with the final word."
"No keep it, I guess that makes sense-" Jeff shrugged.
"Okay!" Jenny chipperly replied. "I am done with the settings. Are you ready?"
"I am."
Jenny hit apply. Instantly a wave hit Jeff. And then it was over.
"So? How do you feel?" Jenny asked. "Do you feel like an 8 year old?"
"I am actually a big boy. I'm, um 16, and uh, big, but then we used the computer and changed."
"That's right." Jenny giggled at Jeff's childish choice of word. It seemed to have work. "But that's our secret. We can't tell anyone."
"Yes! It's a secret." Jeff childishly grinned. "But I think, like, um the mental stuff worked." Jeff said. He was still very much self-aware. An 8 year old was still mature and smart enough the understand what was happening even if he a had a more childish thought process.
"Great. Perfect." Jenny grinned. "Now, do you want to go out and play soccer?" she asked him.
Jeff gave an eager "Yeah!" The two kids immediately went out to play. Jeff was happy to play, and Jenny was happy to have an eager playmate to explore this reality with.
