I think you've just demonstrated my point, M.Ted. And GUEST,Foe, I think you have neatly demonstrated how in practice a lot us do actually learn - whatever theory we may eventually pick-up comes out of doing things without any theory as to why they are the right things to do.

I'm sure there are a lot of people who actually find it easier to start with the theory. Only trouble is sometimes they are inclned to think that the rest of us really work that way as well, and that we're just pretending. There are clearly sveral very different wiring systems people can have in their brains.
