In my most honest opinion, we have gone from a time where our children once were able to listen to their Teachers at School AND their parents as well to where now our Children seemingly dismiss ANYTHING their parents TRY to explain to them by simply saying " My Teacher/s told me this is RIGHT, so you MUST be wrong."
For the first 4-5 of the formative years of child's life the parents, for the most part, are the sole influences upon the shaping of the mind of the child.
But now, it IS whole different story in that, imo, in many cases Teachers seem to have usurped the parental roles almost completely and seem, imo, to be bent upon 'creating' pre- programmed style robotic children, ready to be sent out in to the world to further the agendas of the Teachers.
