Have you ever met someone with a ridiculously posh voice/accent?

Yes, I knew someone with such an accent. It turned out that her parents had been from farming stock in the west of Ireland, and they sent all their kids for elocution training as soon as they family moved to Dublin. I suppose they thought that little kids could be cruel .... but I got a right shock when I met the girl's mother and heard her speak for the first time. They didn't sound related!
