"I wish Angela was ten years old."
"Was something supposed to happen?" said Angela. She still looked seventeen.
"Yes, something was. I wish Angela was wearing a yellow blouse instead of a white blouse."
Peter felt the sensation of something in his eye and looked away for a second. Then he saw that Angela's blouse had changed.
"That's impossible!" said Angela.
"Oh, it's very possible. Now, I wish you were ten years old and wearing all pink clothes."
Which, strangely, didn't work. Angela was still 17 years old, and all her clothes were pink except for the blouse, which stayed yellow. At this point, Peter knew what had happened. Each wish was once only.
Then Jon walked into the room. "Hi, Dad, hi, Angela. Ready for our big date tonight?"
