You pop a couple of white Jelly beans in your nmouth, grinning at your friends. "I sure as heck ain't mucking stalls or changing diapers."
Then you blink, because your freinds and everything else around you starts to get bigger. And bigger. Jake laughs and Ryan makes a noise more like a whinny. Jake says "Looks like you'll need a diaper of your own, little guy!"
Your clothing is falling off, and you stumble over to a mirrored display. The reflection is you when you were 10! No, it's younger than that. You continue to shrink down, 9, 8, 7... When the change finally stops, you aren't tall enough to look over the edge fo the display, but you can still walk. You pull off your way oversized clothes and check yourself out.
You're maybe 3 or 4 years old. Your freinds shake thier heads and laugh and whinny.
