If your brain is tuned to such things you can hear this sort of dialogue in every public venue. It is a manifestation of the subtleties of patriarchal language. I wrote a paper in college arguing that institutional change in education and human rights is nearly impossible because our very language supports these outmoded principles. The mother you heard was most likely treated in the same way. If you had been able to ask her, you probably would have heard her stories of being victimised herself; possibly/probably more than once. But if you could point out to her what her language was doing to her daughter she might not be able to discern the patterns of what she is saying. So many of us are deaf to these subtleties and never once make the connection between demanding our versions of what we may insist is the teaching of proper manners and the future victimization of the indoctrinated child. I was born an outlaw and refused much of my parents indocrination and, even so, was for years victimized in certain situations because of outmoded ideas of power and propriety. Remember, the ruling patriarchs wrote the rules of language and set the unwritten expectations of society. They used the so called rules of civility and etiquette and defined our cultural expectations. This is changing of course in obvious ways but the cultural viewpoint takes longer because the unspoken expectations are so deeply imbedded in our behaviour.
