Read the passage from "Children of the Wartime Evacuation.”

I considered that she was proper middle class while we were clearly working class. I learned to appreciate all these different things from Mrs Coles. I learned how to talk to people and to address them properly and with confidence. I developed a different accent, dropping my Black Country slang. In fact, I have to say that Mrs Coles changed me completely and she loved me – I'm ashamed to admit it – more than my mother ever did. She made me feel wanted. She called us My Boys and that really meant something to us.
