That being said, Elly being a whiny jerk about having to do things for the kids instead of what she wants would be bad enough had she not married her own kind. Her companion in telling her children to have their childhoods where she doesn't have to be oppressed by having to know about them is stupid jackass John with his non-stop need for perfect silence. As we see here, his need to be in a coma when he gets home from work collides messily with his children's need to have any sort of life that isn't sitting on folded hands so Daddy can sleep like a God-damned zombie.
It would be bad enough knowing that John and Elly believe that anything that requires them to have to interact with their children is bad because along with work and work and paying for their retirement, the children owe the two of them being quiet and out of the way because of the sacrifices they don't make were it not for the fact that they cannot and will not connect the fact that they pour cold water on any ambition the children have with the fact that the kids seem to drift through life. Then again, they never do connect their behaviour with what their kids do so that's nothing new.
