Ye Dogs - YANBU.
I can't find the study at the mo, but a University ran one by measuring talk ratios between the genders, within the past few years, sorry to be vague.
Sixth formers were asked to freely discuss certain topics, under the guise of being assessed for how articulate etc they were.
Unknown to them, what was actually being observed was which gender spoke more.
Despite the popular myth that it's women who gossip & won't shut up, poor Stong Silent Menz, hey, the results were -
When boys did 75% of the talking, they reported that the conversation ration had been 50/50.
When girls did 50% of the talking, the boys reported that the girls had dominated the conversation by at least 75%.
I have had a lot of fun, innocently remarking on how interesting this study is to MEN WHO FUCKING DRONE ON AT ME.
But outside of the fun aspect, women not being heard by men is a serious issue. It leads to our medical needs being dismissed, our job prospects overlooked, & just look at the threads on here about how men don't hear a woman's "no" in the domestic sphere.
However, when men address women, they expect to be heard, & woe betide the woman who refuses to bestow attention, gratefully, at a man's whim. Hence catcalling & street harrassment. Women's ideas being ignored in meetings until a man steals them & presents them as his own. The dread, dull horror that is Mansplaining ...
Anyway, if you are ever trapped with this couple again OP, you can cheerfully quote the study. And praise the lord that you are not married to the boring, opinionated twat :)
