This is how it works. The Holy Spirit is continually trying to speak to children. The world thinks that children are to be sent away from their homes to be taught. A strange environment and the continual distraction of other schoolmates causes their minds to be closed to the Holy Spirit. When they arrive home after school, there are other distractions such as television, radio, games and no one to supervise.
Television is one of the more distracting forces.
Moving quickly and full of lies, it is designed to kill the faith of children. I haven't had a lot of television in my life. My mind thinks more clearly when my life is just reality. Any faith that they may have is quenched promptly by the world and the lies it teaches. The truth of the matter is the world hates children and all other humans.
