When talking to a foreigner, say an Australian, do you notice that you mimic the Australian accent without you knowing it? I've caught myself doing this myself several times and I find it quite funny. I have also noticed that this is being done in TV shows. For example, when a foreigner is being interviewed, say a Japanese, the dubbed translation is of someone who speaks in English with that distinct Japanese accent. A little odd but it makes the translation more real, I guess you could say.
