Hey Okema:

Thank you for the interesting perspective!!! The only time I ever heard a Jamaican use an American accent was one time I was driving lost somewhere between Christiana and Mandeville and went down a small lane and two pre-teenage boys in a perfect American accent said variations of "Say, Joe, are you lost?" If I had had presence of mind, I might have replied "raatid! bwai, mi lost"

Thankfully, I did not have presence of mind...
