Ok, here goes...
If there is a better place for this, let me know and I'll move it there. I haven't seen a thread where it really goes.
Okay, I researched personality types and the like last night and I found that some psychologists classify people into one of three donminance classes. High-donminance, medium-dominance and low dominance. People in healthy relationships usually do not date outside their dominance class and peoples dominance classes usuallly do not change. Low dominance women are the type that are easily persuaded and do not make good leaders, essentially they are sheep. In healthy relationships, they date low-dominance men, because the higher doninance classes are too intimidating. Medium dominance woman are a bit better at leading and usually have one or two areas which are their strong suits. They consider low dominance men to boring, high dominance men too assertive. High dominance women are the bossy, confrontational types. They tend to be bold and flashy. Less likely to seek validation and go towards high dominance men because the other types are too weak for them.
The reason that I think this pertains is that based on family statements and things like the Yearbook profile that Casey made it seems that 2 strange things have happened.
One, her dominance type seems to have changed from medium to high.
Also, she seems to have been the type that sought out high dominance men even while she was still medium dominance. Men in LE, usually high dominance. Her mother and her father both seem to be high dominance, as evidenced by her mother believing that she knows everything and her father's outbursts and history in LE.
Casey has gone from not really wanting to stand out, "Jeans and t-shirts kind of girl" to the flashy, look at me type. She went from being engaged to being rather promiscuous, evidenced by the number of boyfriends of late.
There is a definite personality shift here and there had to be something that caused it. I think maybe if we can identify exactly when that happened, we can maybe get some insight at least into Casey, which in turn, migh tlead to Caylee.
Sorry this is so long, I was just looking for an angle that hadn't been hashed to death.
