I don't know whether it's an aspie thing or not, but i do it. i was talking to a girl from manchester, and came out with the word "nurses" in a mancunian accenmt and she stared at me and then burst out lsaughuing. I'm lucky SHE took it Ok and weasn't offended-I've been accused of taking the p*** by others.
Another friend of mine, who is about to be tested, was talking to me about the New York subway system. When she talks about the USA she lapses into an american accent completely unconsciously. The guy accross from her asked what opart of the States she's from and she told him she's British, I don't know what he thought.
