Andrew held the card in both hands and said, "I wish that I was the older brother and that Bruce was only 6."
Immediately, Bruce began to shrink. All of his muscles and mature features dwindled away as he passed backwards through puberty. Soon, he and Andrew were standing eye to eye. At that point, his clothes had become very loose on his youthened frame. And still, he continued to shrink. His pants dropped to the floor as he passed into single digits, revealing a pair of scrawny, hairless legs. Andrew just watched in fascination as his once older brother became ever smaller and more feeble, a real contrast from the strong young adult he had just been. Then, as Bruce reached the age of 6, the changes abruptly stopped.
Bruce stood there in shock, looking up at his formerly younger brother in awe. His too large T-shirt hung off of him like a dress.
"See," said Andrew. "It really does grant wishes."
