In many ways the 'old fashioned' ways of family life have gone out of the window - the family elders keeping the younger ones on the straight & narrow, them issuing orders and the youngsters doing as they're told. It's not the modern way, it seems, kids these days expect to do just as they like and nobody puts them right.
But this is the RF we are talking about, Queenie is head of the country and indeed the Commonwealth, and answerable to the British taxpayers. So, yes I do expect her & the RF to set an example and for her to step in if members of her family behave like knobs & put them right
