I posted something similar to this thought in the psychological thread last week. Teens and young adults KC's age are NOT being held accountable for their actions, for the most part. Whether its b/c of parents both working nowadays, or are just too tired and stressed w/ life to not uphold their rules, I see a lot of spoiled brats w/ big mouths running around. Again, not all young people are like this, but there's enough around that its quite noticable, and quite annoying to those of us that are from an older generation who were raised to respect our parents and authority figures.
A lot of the problem is that for years now, parents could not spank their kids, too afraid of being accused of child abuse. Kids were taken away from parents, actually, because they had "abused" them. Schools could not use corporal punishment, either, therefore kids grew up believing that no matter what they did, they would only be grounded, or have to stay in detention after school for a few days. Kids started disrespecting teachers, their parents, and eventually any adult in authority, to the point that some of them are just horrible people now. Not all, but a lot.
When I was growing up, I got spanked. I also got a belt whipping a couple of times. It did not kill me, and I would not have even thought of going to the authorities. And it also made me a better person!!
I don't think Casey has anything to "hold over" their heads. All they ever wanted was to find Caylee. They are not afraid of her, they were always just too permissive with her, and now it's far too late to do anything about it.
When there is only one daughter in the home, it's easy to place that title of princess on them, and shower them with love and affection to the point that it makes them selfish and hateful. Now they are faced with the fact that their precious granddaughter is dead, at the hands of her own mother, and they know there is no way out of this nightmare. I would imagine that they keep hoping and praying that they will wake up and it will all be a bad dream, but they know that's not the way it is.
I feel so bad for them, because their lives must really SUCK right now!
