Also late at night Jeff's younger sister Karen sat in front of her laptop and made a check up on the network. Although Karen was three years younger than Jeff she was the a lot more intelligent than Jeff. She worked most of the day on the computer and that was really uncommon for a 13-year old child.
When the check up was complete Karen found a strange new programme on her laptop. It was called Chronivac 4.0. Karen started the programme and when she read the instructions Karen grinned.
This would be the chance to revenge on Jeff, who could be very sinewy and made all times jokes about her and her hobbies.
But now it was her turn.
What could be the perfect punishment for Jeff?
