In my college Sociology class, my professor ran us through a couple situations, then ran them back for us. Gender-wise, women tended to make small interjections, nod their heads, etc, as the conversation went among, to indicate that they were listening. Which apparently leads into two “classic” complaints between M/F partners.
Men tended to think that women were “always changing their minds”, because the men interpreted the women’s nods and interjections as agreement instead of “I’m listening to you”.
And women tended to think that men “weren’t listening to them” because men never provided this feedback.
It’s cute, how they’re saying it won’t be a strain on the city water system or the industrial supply. They’re not denying that it’ll strain the overall water supply, draining aquifers or lakes or whatever, just that it won’t affect these specific water supplies.
