As well as she and her and he and him. My mother (an English teacher) used to blame it on TV because even the “talking heads” made glaring errors (as they still do), to say nothing of the colloquial speech of the actors (which is forgivable if it mirrors the characters they are playing.)
My grandfather was a teacher. He died before I was born but my mother told me he was a grammar expert. She had even saved a paper where he had diagramed the sentences. Do they still teach that? My mom was an expert as well with only a high school education. My children use correct grsmmar and it makes me very proud. Correct grammar makes you sound smart.
