Maybe Chrustie (being the diva and model she thinks she is in her head) felt guilty getting her nails done alone so she figured she better get Cain's done too. It would in her mind justify her getting it done and make her look like a good caregiver. My feeling is she doesn't have the money for it, could have used to money to support themselves and buy food etc and she could have painted his nails black at home. What boy would want to have this picture taken and possibly be picked on and made fun of by bullies in school for getting a pedicure and his picture taken to prove it. Heck he's already got as alcoholic/drug addicted mother and had this story strewn across national tv and everyone knows his grandmother is an addict and homeless. Why not just hold him down and let the kids pick on him for crying out loud. Chrustie doesn't do anything for anyone but herself. Who takes a camera to a salon when they get their nails done BTW?
