First, apologies if I've misappropriated the term "male gaze".
This is what happened: DW and I went to visit an independent girls' school to see if would be a good fit for DD1 and DD2 later. All was good with the school, the emphasis on teaching "the whole" person not simply an results factory. The site is various buildings linked together with corridors and stairs: and this is where it happened. The girls were walking up and down the stairs making no attempt to wrap their skirts around their knees, nor looking to see who was "checking them out" ... they were relaxed, going about their business, unaffected and un-threatened. It struck me then that this is how girls and women do not cannot? behave in wider/mixed society. To an extent, I get it now.
And in case anyone is wondering -- yes, I made sure that I didn't stare and didn't break this happy state of affairs.
