Mine started a long time ago. When I started at Oxford in the late 80s someone told me, ‘You can’t possibly be studying English at Oxford with an accent like that!’ This came hot on the heels of a teacher at a study week telling me ‘The northern accent is generally associated with being thick.’ I now teach on the outskirts of Birmingham and it’s lovely listening to some of my A level language students who are really proud of their accent despite the prejudice they encounter. Same kind of things I was getting back then.
