So... New England accents.
There are lots of different ones. For the best examples in films, see The Depahtid and The Russians a-Comin, the Russians a-Comin.
Other New Englanders do not generally think I have too much of a New England accent.
Southerners generally think I talk like a Yankee. I have no problem with that. I did not, in fact, know that "Yankee" was considered a pejorative term in the south until a well-meaning southerner called me one and then apologized.
But here's the thing: Due to years and years of living in New England, I somehow just discovered yestiddy that "pejorative" is not, in fact, "perjorative." God bless spell-check.
