I read your post completely. I like it. You have tried to capture a lot of important points in your post. But remember one thing that after a child is born parents take care of him a lot. And through many important things make him like a human being and come to a stage the parent sees that his child has reached a good stage then the parent has nothing to do and the parent is helpless then if the parent does not take the responsibility of the child. Then there is no way they have anything to do. Of course, it is our responsibility to respect and accept the responsibility of our parents
