She does.

Claire turned around in shock when she noticed the sound of two car-doors shutting instead of just her own, Paulette grabbing one of her hands.

"Paulie, what are you doing?"

"I'm changing you."
"I don't need you to change me. I'll be fine."

"Your my baby sister and its the job of the big sister to change the baby sister when she poops herself."

Claire blushed hard at how causal she was being. Claire has had her diaper changed in public all her life (as had everyone else in her age group in this town), but she was still a teenager.

"But I don't want you to!"

"Why not?"

"Because it's embarrassing. I don't want you telling everyone how messy I am."

Paulette's eyes wandered to another girl Claire's age -- a brunette in a lavender dress and a yellow bow in her hair -- only a few feet away who squatted down, grunting until her diapered butt ballooned and then dropped like a weight.

"Yeah. Sure."
