When I was growing up in La República de Tejas, the stories included in our elementary school reading textbooks were often slightly mystifying to me as they were often set in New York or New Jersey or somewhere and talked about things that ordinary kids were supposed to identify with but had nothing to do with life as we knew it down there. References to some fat kid getting Italian ices in front of a brownstone, or whatever.
One thing I never could figure out later, though, was some dialogue between a kid and his father about the kid’s dog. They were having an argument and the kid said something in reference to his mother, like “she lets me take the dog in my room!” and the dad whirled around and bit his head off: "DON’T you call your mother “SHE!” This happened at least two or three times in the story.
So, in one of the myriad cultures of the Yankee states in the 1970s or earlier, was it ever considered egregiously disrespectful to refer to your mother by the feminine third person pronoun? What were you supposed to call her, then?
A small mystery from my yute.
