Hrm... I'll note it down so I would remember to locate the line wherein it was mentioned. 

 - I found it somewhat interesting that your last IC post would mention accents ... the one I myself most commonly use when speaking English (my, eh, performance-accent? the one I also use when addressing an audience?) is apparently strange. One of the people taking the verbal part of my English exam back in the day commented that it was interesting, and added that it was somehow very easy to understand, but he had never heard something quite like that. (It might have somewhat changed after that, though, since it's been a while. Accents do change over time, and quite a lot.)
Else I tend to just match my accent with the people I am currently speaking to ... and sometimes my brain gets confused (especially if there are several nationalities together, or I am dealing with something in another language on the side) and then I may pronounce the same word in one way in one sentence, and in another in the next.
