Learn about *what* exactly? What's on TV or the internet that they simply *must* learn?
That was really a reference to the "world outside".
I don't know if you have kids or not...
Three - all in their 20's now. And nothing pleased me more than when they worked out that something was "wrong" based on their own experiences, rather than me having to tell them so (at which point they often disagreed, and usually put up some good arguments for their views).
So I prefer to give general guidelines, let them know that I'll (try to) help with any problems then let them get on with it. They did things differently to how I would have done them, but it all worked for them, and I reckon they're the better for having their own experiential learning, rather than any proscriptive edicts from me.
