Mark held down the button and watched in amazement as his eighteen-year old sister suddenly shrunk in height, and in the blink of an eye, became an eight-year old girl!
Her clothing had completely adjusted as well. She now wore a tiny, white and pink t-shirt with various cartoon princesses on it. She had on a small, pink skirt, some small, ruffled pink ankle socks, and a pair of white and pink tennis shoes. She now stood atop a tiny stool to see her reflection in the bathroom mirror.
"What?" she said in a tiny voice, turning around and catching Mark standing there staring at her. "Haven't you ever seen me brush my teeth before? Mom! Mark's bugging me and bein' weird!"
From down the hall, Mark heard the voice of his mother: "Mark Kremzer, leave your little sister Jenny alone!"
It really works, Mark thought. I just changed my older sister into a little kid -- and nobody is any the wiser!
