My dear butler, I assure you the do-nothing game IS a traditional Belosian game. Indeed, I cannot believe that there is a country where parents have not tried it.
I mean, I imagine it's only played a few times per family per generation, until the parents realize it isn't going to work (and/or that things get horrifying quickly when the children inevitably try to cheat—making trouble as covertly as possible). :'p
