Another thought. For reasons too long and involved to go into and which probably don't really belong here, I've been writing a cycle of stories featuring "South African" characters.... now all I really intended to do originally was to write a character who embodied what you might think of as all the worst, hardest-to-love, manifestations of "White South African-ness" as a minor player in a larger tale. She was deliberately written as somebody who her friends and colleagues would find exasperating and hard to love - although with one or two redeeming characteristics. That would or should have been it: everything you suspect about Afrikaaners taken Up To Eleven, as fitted the black humour of the story. Except that wasn't it and I started writing more and evolving the characters. And it dawned on me that, as a white Brit with no previous connection of any sort with South Africa and certainly no national or family links, that I'd better do the bloody research concerning that about which I was writing and it might not be a bad idea, if my central characters were Afrikaans-speaking, to stop winging it, and move on from my deplorably cavalier practice of hopefully throwing in something that was vaguely Dutch/German, to illustrate that language. And thus your author started to learn a new language and its idioms and found it surprisingly easy to get into. Nowhere near fluent, but languages in the Afrikaans/Dutch/Flemish arc really do make intuitive sense to me, far more so than French ever did.(total immersion in things like "Salamander" on TV help with Flemish, I have to say...)
And that childhood feeling, discussed earlier in this thread, about Australia and its magical sunlit wide-open spaces and sense of wonderful expansion... damn, I'm feeling that now about South Africa, another country I've never visited. Is this just a result of immersing myself in a country and its culture or is something deeper going on here?
