Casey is a spoiled brat with a borderline personality disorder that has been undiagnosed or ignored by her parents.
Goggle this disorder. To the one who has it you are a friend or an enemy. You can be, in the sick person mind get changed back and forth from day to day, hour to hour even minute to minute. The people dealing with this, especially if they do not understand what is happening end up looking just a nutty as the sick person.
If you can convince the one with the disorder that you believe her fantasy life then she will share bits and pieces of her fantasy life. They are always in the process of creating a new plan to make this fantasy life happen. If you show any signs of not believing her fantasy then she hates you, shuts you out and will clam up. They are the center of everything. The world revolves around them. All of this girls actions, her indifference to her missing child, her self absorption, her concern about not speaking to her boyfriend and her demand for his phone number, her tone with her parents and her not co-operating with LE. Casey speaks more freely to her mother and brother. Her father is LE he is an enemy. Lee questioned her. Is there anything else you can tell me about where she (Caylee) is? Casey reaction is short and snotty. Casey acts the same with the girlfriend on one of the calls. Listen to them again. Listen to how Casey responds when questioned as to how she responses if the caller is in agreement or accepting of what she says. Go to youtube and listen to the tapes.
Caseys new fantasy life is Tony will be her new soul mate and she will do whatever she has to make this plan work. Is Caylee part of the plan? Do not known. She did take the little girl over to Tonys so maybe at first. The plan may have changed.
I my little sister has this and it took us years to figure out what was going on. She was 41 when the fit hit the shan. When we all sat down around the table and starting comparing notes. That was when we finaly realized OMG she has been conning us for years.
