Katie closed her eyes. For some reason her most fond memories were of being seven, being in the second grade. She'd had only a few friends back then, but she couldn't help but want to be a second grader again. She went out and bought all the supplies she would need for going to school: backpack, pencils, lunch box etc. She made a wish with the ring that the school would have fingerprints on file for a little girl her age, and she even thought ahead to wish to convert one of the rooms in her swanky house to a seven year old girl's room, but one fitting her tastes. When she was pleased with the result, Katie knew she was ready.
"I wish that I was seven years old again, but that I still remembered being a grown up, and how to use the ring, but would be who I should be as a seven year old."
Almost instantly the ring warmed on her finger and Katie felt the familiar tingle as her body began to regress. She closed her eyes and felt it happen, felt the world growing around her. She felt her body fall back through puberty as her mind began to make subtle adjustments in accordance with her wish. When it was done, Katie opened her eyes. Her second grade picture smiled back at her, complete with a missing tooth and the freckles that dotted her button nose. Her hair had been pulled back into a ponytail by a pink scrunchie, she wore a pink shirt, overalls and pink high top sneakers. In all she was the exact image she'd been when she first found the ring, though she didnt remember it that way.
Picking up her backpack, Katie set out for school.
