..That joke with the priest that said "do as I say, not as I do"?
(Wiktionary says: This order first appeared in John Selden's Table-Talk (c. 1654): "Preachers say, 'Do as I say, not as I do.'")
I watch V, he is learning, every second of his life.
He is learning how this world works, how his body works, how interaction works.
Does he learn from what I say?
A bit, when I insist, I explain and I plead.
But the biggest part from his learning he does by watching me.
He learns from what I do.
I believe we are all like this naturally - but we the grown-ups seem to have learned to only (mostly) believe the words and not the actions of people around us.
In marketing school I even learned that people believe it more if they see something written - so I'd better write all kinds of convincing "facts" (read: lies) on my website - in order for people to buy what I sell..
Of course, this opens the door for everybody to write whatever they think fit - and declare it "truth"..
