I am reminded of a scenario where a group of Arab oil sheikhs and British oil executives met in London, and in Arab countries, men kiss each other on each cheek as a greeting, like Westerners shake hands. Also, Arabs stand closer to each other when talking, and the British executive would take a step back and the Arab was affronted, and he took a step closer. We communicate differently.
When it comes to assumptions of arrogance, what people tend to forget is that if an autistic person knows the details of something and the person they're talking to gets it wrong, we tend to need it to be right for us. For example, I was watching Who Wants To Be a Millionaire years ago, and the question put forward was, "How many elections has John Howard won as leader of the Liberal Party?" and the answers were, "1,2,3,4," and I would have said, "Okay, if you mean how many times did the Liberal Party win government with John Howard as leader, the answer is three. If, however, you mean, how many elections did John Howard personally win the answer is four, as while he did not win government in 1987, he retained his seat and the leadership of the Liberal Party." Hopefully, the host would have said, "We'll check with the adjudicators." That's not arrogance, it's needing to understand things.
