learning any dialect or language in addition to one's own, adds to one's ability to communicate and more fully immerse, when in cultures other than one's own. After living around west indians pretty nearly all my life, and spending so much time in JA and other parts of the caribbean, i understand most patwa, and can speak it as well, although i typically don't speak that way on an everyday basis. but when in jamaica, among good friends, it adds better understanding to our conversations when we can all speak the same way. they feel more at ease with me, and i can participate in the conversation much more fully & easily. in general, i feel that speaking as many different languages and dialects as possible, adds to the enjoyment of traveling, and of life in general -
