...My American wife is at times dedicated in her attempts to teach me the colonial dialectic version of English with which I am confronted here in Michigan on a daily basis.
People here in Maine sometimes remark that they can't figure out where I'm from. I am from Arizona, but spent a good deal of time in California; the dialect is not different between these two.
Once I explain myself I sometimes assert that I am actively resisting adopting the dialect; when I get used to the area enough to say "Ah'm gonna go pahk the cah in the doohyahd," it's time to go back.
This piece of bluntly delivered (not all that many Mainers actually talk that way anymore) news is not always received with humor, but that's okay.
More on dialects, not reading:
