"Oops," Jon said, feeling the stone grow warm in his hand.
"How could I not be happy, Jon? This has always been my biggest fantasy," Karyn said.
"Really?"
"Yeah. Ever since I was a little girl, I always wondered what it would be like to be invisible. And now I am!" she said, excitedly. Then she started to take off her clothes.
"Karyn, what are you doing?"
"I can't be totally invisible if I'm wearing clothes."
Soon, all of her clothes were on the floor and Jon had no idea where Karyn was.
"Karyn? Where are you?" He waved his arms around in front of him, right around where Karyn was before, but there was nothing but air.
"I'm right here," Karyn whispered in his ear, from behind him. He was so startled that he jumped at her voice.
"Karyn, you scared me."
"I know. Isn't this so cool? Thanks for making me invisible."
