When writing about different cultures we need to realize that in some situations, the culture, standards, code of ethics and traditions are completely different. Don’t just presume that because you would do a thing one way, so will all other cultures. See below for some cultural differences to watch out for.
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.
