English as a language
Before I became a writer, I believed English was one language. Wherever you lived, if you spoke English, you . . . spoke English! By the same token, if you wrote English, you . . . wrote English.
Obviously, my way of writing English was the correct way, the only way. After all, I was English. (Scottish actually, but we’ll ignore that.)
Because I grew up in the British Colony of Rhodesia (now Zimbabwe) most of my books came from England. They were printed in the same English as my teachers taught. I moved to South Africa to study nursing, and all my textbooks were printed in the UK.
