"I wish that the Sarah Jen referred to, when wishing she would wake up with everyone thinking she was a boy, was Sarah Smith, not Sarah McMillan."
"Wait, who's Sarah Smith?" John asked.
"I don't know, does it matter? We didn't write a last name, so I just said the first one that came to mind."
"Poor Sarah Smith, wherever you are" whispered John.
The rock grew warm and they assumed it had worked. To test it out, they text a friend to casually ask for Sarah. From their reply, they knew it had worked out fine. It was a minor celebration, John realized, as Sarah's wish hadn't said "John", it had said "YOU" while directly pointing to him. He'd have to find another way to phrase his wishes later.
After wishing something similar for Carl, they started debating about the best way to wish to reverse Karyn's wishes. She had said "I" instead of naming a third person and she had wished for direct changes, not only how other people perceived her, so it was going to be trickier to wish around them. Still, having found a way, Karyn proceeds.
"I wish that the 'I' in my wish for blonde hair and big boobs referred to I Smith, not me, Karyn Black" said Karyn.
"Karyn, you're evil. That's not the wish we wrote down... and I doubt there's someone called 'I Smith'"
"Still, the rock got warm and look.... my boobs and hair are back to normal" celebrated Karyn. "Ah, it's such a relief... Anyways, Jen, what do you want to do now?"
"Uh, not much... I should be going already" said John and after hugging Karyn goodbye, he found himself walking home, thinking about how to reverse the 3 wishes affecting him.
