I can't speak for the majority, but for myself, I am not against them. All I want them to do is make thier daughter be responsible by stepping back and allowing her to clean up her own mess, and stop lying to cover her. That is all I want. I think most people are angry with Casey and she just happens to be staying with her mother, so that anger is crossing over to Cindy for allowing her to stay there.
I know, I think that is what most people expect they should do. I, at times myself, feel exactly the same way as you do. But really, it's easy for us to sit here and judge them, believing we would act differently, but the reality of the situation is, unless we were in their shoes, we don't have a clue how we would react..
