Exactly Anya- when we were kids we did get bored, and there was NO tv or any electronic gadgets, etc- and after a while we did think of something to do, to create, to climb, to draw ... whatever. But how how does one 'pretend- artificially and with the GCs knowing full well that the tablet, game console, etc- is just there behind the cupboard door- without them seeing in as a 'punishment and denial'? Same for money- we had none, and we knew there was none- my GCs know that there is some... somewhere not far.
Really not sure what the answer is. Our GCs are also taken to rubgy, swimming, ballet, Scouts, etc, etc- they only have 1 evening free of activities. Here the kids say something like 'going to the woods with x, y and z- don't worry got my pen-knife- back around 7- bye' same as I did in the 50s.
