Katie grinned as she and her Mom walked through the Mall. This was becoming more fun than she originally imagined, and her Mom effectively was becoming like the sister she always wanted.
"Maybe she could be, then she wouldn't be so bossy," Katie thought. She'd wanted a twin sister or any kind of sister for most of her life, and now she had the chance. Of course, she still had to get home after this, but for now she could close the distance between them and get some new clothes at the mall to suit her new sister.
"Hey sis," Katie said. "Lets get you some cool new clothes!"
Kelly looked at her clothes and nodded, "Yeah these old things are like something someone without any sense of style would wear!"
The two began to browse and Katie made her wish. "I wish that Mom would become seventeen and think she was my sister and act just like she should at this age."
Kelly meanwhile was starting to gather some clothes, but as she did her old ones started to become big on her. Katie watched as years fell away as she became a beautiful young adult. Then she slipped back even further into her late teens, and then, back into her mid teens. As she did her sense of style changed, and she huffed as her old clothes hampered her movement.
"Im gonna try some clothes on, okay tweeb?" Kelly said.
"Tweeb?" Katie wondered aloud.
"Yeah, duh, you. YOur a tweeb, tween and dweeb." Kellie said, poking Katie in the forehead. "You should get some new clothes too, those are like....little kids clothes."
Katie frowned at her old clothes. She hadn't changed her own perception of herself, and she wasn't sure her mom's new attitude was one she liked. Still she got some more clothes fit for several different ages so she could experiment. Finally, Kelly came out wearing a nice new outfit.
"Alright Tweeb, what next...?"
