"Is it you, Jon?" asked Jon's mother.
"Yeah, Mom. It's me! That stone's mine! Grandpa left it to me for real. You realize what you did, right?"
"I do now ... I wished you could be more like Karyn. Now you're her twin sister Joanne and I'm like this. I know you can't reverse wishes, but there has to be a way to fix it!"
Joanne thought. "I think I can. Look, Mom. You didn't say anything about wishing to be in a 7-11, right?"
"No ..."
"Well, you can't reverse wishes, but you didn't really wish to be in a 7-11. What exactly did you say?"
"I wished you'd be more like Karyn."
"Hmm ... how about this? Just wish to be back in the same house and ... well ... here, let me take the stone."
Jon's mother looked all around herself. "That may be for the best. It seems that I can't use it right. Just look at what I did with just one wish!"
Joanne took the stone from her and said, "I wish that Mom has her house, job, and most of her history back from before the wish, to make me more like Karyn, was made."
The stone glowed, but nothing happened.
"Oh, I hope it's not broken," Jon's mom said.
"There's probably a very good reason for what just happened," Joanne said. "I wish to know why my last wish wasn't granted."
New information filled her head and she realized her mistake.
"In this new reality, you're not my mom. Karyn's mom is my mom. So, the wishing stone changed reality for her instead of you."
"Oh, Jon. It seems like every wish we make things get worse and worse."
"Don't worry, Mom. I can still fix this," Joanne reassured.
