I'm not sure it hit exactly what he was asking.
If I can try to hit it, here's what I THINK her opinion is like- and she may correct me and disavow it.....
She knows how water gets to her faucets, and knows that there's steps involving collection,
chlorination and flouridation, transportation, water pressure and so on up to the moment
it reaches her spigot and she turns the tap.
She takes for granted that there will be water reaching her home whenever she wants.
She doesn't think about the steps when she turns the tap.
She knows how electricity is generated at power stations of various kinds (with fossil
fuels, or hydroelectric, or nuclear, etc). She knows that there's alternating current cables
that carry the current from the power station to her home.
She takes for granted that the electricity will be there when she turns on the light switch.
She doesn't stop each time to consider whether it will or not.
PERHAPS that's what she means, but she'll need to say "That's it" or "Not even close" or
something like that.
