Highdose you ain't that bloody posh ! I knows where you was borned.
My wife used to maintain that everybody else spoke with an accent , ours was just correct, she also used to say of someone with what is described as a "cut glass" English accent, "they aren't born talking like that " implying they had taken lessons in how to talk like our dear Queen.
She now recognizes that we have one of the Kentish accents.
I find regional accents fascinating, and regional expressions and idioms, we have become so cosmopolitan now that many accents, and languages and dialects are heard on our High Streets, viva la difference !
