As he came back in his room he saw his 13 year old sister Lisa just hitting enter on the Chronivac.
"Um hey Jeff," Lisa nervously said "I figured you would be back down here soon, I heard you earlier when you passed my room, and went to ask you a question, but when I opened my door and l looked to see where you were you looked much older, so I went to see what you had been doing and I saw this thing."
Jeff trying his hardest to not give away his concern calmly asked, "What did you you just change on there? Don't lie to me I saw you hit enter, I won't get angry just tell me."
Lisa scratching a mild itch she had, but much less nervously replied, "I saw a text box with a number 17 flashing and figured you had aged yourself to 17, so I pulled down this drop down menu with your name and changed it to mine, then I entered an 18 as I was always curious what I would look like older and hit enter as you were rounding the corner, and well you know the rest, I am going to go to the bathroom and see if this thing works."
She got up to leave and Jeff rushed over there to see what screen she was on and noticed she still had up the hairy package screen he figured in her haste Lisa must not have read what the program did, she always was a little impulsive, the timer on the screen displayed that the transformation was about to start and would last 120 seconds. This worried him as he remembered that the package had said it was not intended for girls to use it, and he ran to the bathroom where his sister was behind the locked door "Lisa, are you okay?"
He heard some rustling which he assumed was her taking off her clothes to watch her change, and heard her say "Go away Jeff I want to watch this in peace, I am fine, in fact better I am about to be 18."
Jeff a bit annoyed with his sister replied "Lisa I don't think you are going to like what is about to happen, you really should read before you click things on computers." especially reality altering programs he though.
"You are only angry cus I am about to be your older sister." was her reply
"Sure you are," he thought, "well time to wait and see what happens, I am sure I will have to fix it for her, but maybe I will let her worry some depending on what happens to her." Jeff took a seat at a nearby chair waiting on what is to come...
