I don't know what a frontal adverb is (my mind performs an emergency stop at 'full frontal'*) and I write (and draw pictures) for a living (I know, I know, laugh it up, you ain't seen my pay cheque – and if you have, I want it back). I don't feel especially deficient. I come from that generation without grammar, we just had words at my school. Considering we all spoke Erewashian, which as dialects go is pretty much a glottal apocalypse where consonants fear to tread, I think mere words were challenge enough.
I did recently read a book about grammar I found on my wife's desk (she's a writer and editor) which was awfully dull, so I pity the kids that are subjected to such enhanced grammarification techniques. What are the adverbs in this sentence, it would demand. I don't know. Or more I didn't care. Sentences either sound good or they don't. Much rhetorical flourish, I'm sure, is defiantly ungrammatical.
Reading about kids and schools these days, I'm glad I went when I did, before we slapped a target on everything and didn't believe anything that didn't come with a checklist.
*Yes, I know, on re-reading it's 'frontED'. Freud wrote that book, not me.
