My three year old knows not to run in front of cars or not put his hand into a fire, that is, most of the time - but I can't take it for granted. He could have an illogical moment and do the wrong thing - that's why it is my job to hold his hand if we're near a road, or have a fireguard over the fireplace - I have no right to smack him for not retaining some information his brain is just learning to be equipped for.

well said bro.
Have you noticed how right on the comments in the Herald views have been? The public's not as silly as some people think.....
