What I would like to know is if this personality we are seeing and hearing from Casey is her normal personality. The parents don't seem to state anything is remiss yet Casey's behavior is beyond odd!!! Even the lawyer doesn't mention how odd she is. She has no voice inflection. No ability to get angry. No ability to get sad. (except to cry for herself when they started talking about the child being dead and he jig is about up and the huge bail that was being set for her). She has no ability to get upset or anything. Does this girl live on some of those heavy drugs for schizophrenics or what? Something isn't right here. I want to know if this is her real self or she got this way recently. I can't believe the parents could think there is nothing wrong with her.
This is my opinion: When I heard Casey's voice on the 911 call, my first thought was SHE SOUNDS NUMB.
For 31 days she has not been sleeping, she has been withholding the fact that her daughter is no longer with her, she has been going to bars and drinking and acting as if nothing is wrong.
Even the best liar in the world feels stress, and cumulative stress can lead to emotional numbness. I would consider keeping quiet for 31 days, not telling her mother Caylee is gone (I will not define what *gone* could mean), and having to keep her statements straight would be extremely stressful.
