He held it in his hand and said "I wish that for the next seven days ..."
Jon stopped himself. It was a little unfair to change someone's personality without them knowing about it. He didn't mind it with Sarah so much, but Karyn was his friend.
But now he also had an unfinished wish, and he knew he had to handle it carefully. "Uh...I won't get sick?" He hoped that would be fairly harmless.
He picked up the phone and called Karyn.
"Hello?" Asked the voice on the other side.
"Karyn. It's Jon. Want to come over and try out the you-know-what? I've thought of an interesting way to use it."
"Sure, Jon-boy. Will it help take care of my...er..new assets?" Karyn asked awkwardly.
"Well, I guess you could say that.."
"I'll be right over. Bye" With that, Karyn hung up.
