Children after the age of 5 are well on there way of establishing conversations with everyone but their parents. They know no boundaries to anything, they ask when they want to know. By that time they are out of the house and already living a life that is quite different from their parents. It happens, it's called growing up, and they do it when their parents are at work, or busy wearing all of their own many hats. My grandchildren are better technically than I am. They know how to push buttons to do what they do. Ever see a child play a video game, they are quick, it's parents who slow down, it's called aging.
