"...let's make you act the part!" Leah's anxiety reached a peak, as her body and will was no longer her own. To keep her parasympathetic nervous system from going critical, her mind was forced to drift into an out of body perspective, and Leah fell into a dissociative state. Her eyes glaze over as her consciousness leaves her. Tina cleared her throat, trying to get Leah's attention, but realizing it was a lost cause.
"You know, I've always wanted to put you in diapers; I'm so happy I can now. Sorry Leah, but...you just aren't meant to be a big girl, and trying so hard to be one is just making you miserable.
