Holding the stone, Karyn said "I wish that for the next," she thought about how long it would take to get home, "10 minutes, Jon will be invisible to everyone, except me. There, that should do it."
"Yeah, but what about me!" yelled Jon, in panic.
"What about you?"
"I can't see myself."
Karyn thought about what she wished. "Oops. I forgot to include you in the wish. Sorry."
"How am I gonna get home if I can't see myself?"
"I'm here. Don't worry Jon-girl. It's only gonna last 10 minutes. Eventually you'll be visible again. But we better get going if we're going to get home within ten minutes."
"Okay, fine. Let's go. Umm, maybe you should hold my hand. You know, if I trip or something."
Jon held out his hand and Karyn grasped it. "Okay, let's go."
