British versus American English. ( Archived) (61)

It´s really due to the amount of time spent as a non native speaker of English in an English speaking country. We automatically parrot another language in order to be understood, as children do when they start to speak. This becomes more necessary for adults the longer they spend in another country, except for the Spanish ex-pats, who often try to speak Spanish loudly without heed to pronunciation or accent. To be fair though, they don´t need to learn the language if they are living in Little Britain communities as many do.

It´s interesting that you spell in the American way though, some of my students, particularly the younger ones, speak with an American accent because they have spent a lot of time watching American films/movies.
