Learning a language is hard. This whole thread is the differences between nations who speak the same language. If they can't agree what chance has a non native got? As a native English speaker I appreciate that I don't need to learn another language. But on the other hand, the language has also become the worlds language, so its about as fair criticising the Dutch for sentence construction, as it is for criticising Australians for making everything into a question?
