"The wishing rock," Jon's mom said, with tears in her eyes. "So you have it now. I hope that you're more responsible than I was. Your grandfather trusted me with it, to use it properly and I didn't."
"So," said Jon, "Is it true you used to be male?"
"So, you know," said his mom. "Yes, I was a boy, until I made a careless wish. I made a lot of them, but that wish was what caused your grandfather to take away the stone. I don't know how he knew what changes were being made, because the stone is supposed to change other people's memories. Maybe its because he found it, or he made a wish to know when wishes were being made, I don't know. But I was being stupid. I was changing stuff, serious stuff. I knew the wishes were permanent, but that didn't stop me. Finally, I made a wish to be a girl. I can't remember exactly how I phrased it, but after I changed, my father came in. He knew what I had been doing and how I had been irresponsible. He took the stone from me and was able to find ways to fix most of the damage I had done. But we weren't able to find a cure for my sex change. I was stuck as a girl because I couldn't remember how I phrased the wish, so my grandfather couldn't figure out a way to reverse it. So I had to spend the rest of my life as a female. It was hard at first, but I got used to it eventually. Everyone but my father and I remembered me being a girl, so they didn't treat me like a freak or anything. Eventually, I met your father, fell in love and got married. When I gave birth to your brother, Matt, I knew that I didn't want to go back to being a guy. I was happy as a woman."
Jon was stunned. This changed so much. His mother was a boy, stuck in a girl's body because of irresponsible wishing. And now a careless wish had given Karyn big boobs and long, blone hair. What happened if they couldn't find a way to reverse that wish and Karyn was stuck like that, the same way that his mom was stuck as a woman? He noticed that his mom had started to cry. He hugged her and she hugged him back. It couldn't have been easy of his mom to make an admission like that. He promised himself that he would be responsible for his mother's sake.
