Zack made the wish. "I wish that it was normal for all eighteen-year-olds to act like Susie does, because now preschool starts at age 22 and all ages below that are like babies."
Susie didn't change, but Zack did.
First he saw the chair he'd sat in turn into a high chair like Susie's. Then he looked in a mirror to watch his clothes change. His pants and underwear bunched up into a big, bulky disposable diaper. His shirt stretched over the diaper and became a onesie, turning baby blue in color. A bib (already messy) appeared on his neck. A clip appeared on his shirt. From the clip came a ribbon, and at the end of the ribbon was a red pacifier. The pacifier then popped itself into his mouth.
