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.
I don’t think that I could still diagram a sentence, although I used to be quite good at it. I don’t remember my kids bringing home homework on that topic. More’s the pity!
