"I have a magic ring that grants wishes." I said.
"Do I look like I'm in the mood for childish games?" snapped Jessie.
"I'm telling the truth!" I said "I'll prove it!".
I decided not to make her naked again but instead wished for her chair to levitate. Jessie found herself rising up off the ground.
"ALLRIGHT!!" she cried "YOU'VE TELLING THE TRUTH!". I gently set her down. "Can that ring really cure my brother?" she asked.
"Sure!" I replied "I wish that Jessie's brother was cured."
The ring tingled but died down. I sensed in my mind that the ring hadn't worked.
"Well?" asked Jessie hopefully.
"I'm really sorry Jessie." I said "Guess the ring doesn't have unlimited power."
