My late friend Barbara said I spoke French with a Boston accent.
Even today if I meet an American they immediately say "You're from Boston." It is true -- in 26.5 years I still have an Ahnt not an ant, a cah not a car, etc.
I will never pahk my cah in Hahvahd yahd even when I am in Boston. If you look at the photo you can see it is a grassy area and I'm sure the Hahvahd police would arrest any drivah ruining the grass.
Imagine my pleasure this morning when reading Lucifer's Banker the writer Bradley Birkenfeld said "A real Boston accent is like having a swagger: you either have it or you don't."
I've a real accent and I guess, by definition, a swagger.
I can live with that.
