Accents

Hmmm I hope there isnt another thread of this anywhere... But I realized something ever since I came down here to the states. Why is it, that in America, everyone in different parts of the country speak with a different accent when we are all speaking the same language? Same with in Canada, apparently people from Ontario say "eh" more then people from Alberta, and we all talk differently as well. I can understand some reasons for Ontario, becuase there are more bilingual people there compared to over in Western Canada, and Eastern Canada is where more of the French speakers are, some are in BC as well (which is the farthest province in the west) but not as much as over in the East.

Sooo, opinions?:words:
