Idiot sister, crazy mom

Seriously how stupid is the sister, I mean completely brain washed. How could you not see that your mother was a total nut job and I am not just talking about the sister character in the film, I mean the real sister. And that post she left wow, she is totally a crazy, brain washed b**ch. There are just some people out their who will believe everything they are told by their parent, and follow it to a T even when they are wrong or crazy. And about the mother, what a way to show both your children you love them.
