Katie was tired of her Mom's lack of respect for her. If she was going to still treat her like a kid, then she'd be a kid.
"I wish Mom was my thirteen year old sister!" she said. Almost immediately she felt the ring warm and she saw her mother start to change.

She recognized the freckled face from her mother's seventh grade picture. The girl in front of her was wearing similar clothes and sneakers to Katie, her hair in a ponytail. She huffed an errant strande of hair from her nose.
"Sis? you okay?"
