"Wow you look fine, I thought wishes couldn't be undone, are you ok Jon?" Karyn asked. Sarah could feel the familiar stone in her hand, "don't jinx it, wishes can be changed not undone, I fear that the effects just haven't happened yet" Sarah said in a perfect Jon impression. Karyn looked sympathetic obviously believing every word. "I hope you will be ok, I'll keep an eye on you" she said sadly.
"Don't worry, I'll figure it out" Sarah replied hugging her friend "at least you are back to normal" she said thinking of the horrible things she could do to the girl who had insulted her for years. But first Jon would pay. She laughed in a nervous Jon way, "anyway we have a test to get though first"
The two wondered towards class together, but separated to use the restroom, Karyn wanting to see her returned body and Sarah wanting to get out of Jon's skin.
"I wish I would painlessly turn into a hot blonde woman during the day, with my idea of the perfect body and looks and only Karyn and Jon would notice any difference, the rest of the world think Jon was born a girl and my new parents had named me Sarah" she giggled, "now to fix the new Sarah"
