It also happens in other languages as well. My Montreal French sounds very strange to a Frenchman, and vice versa, and what the Cajuns speak in Louisiana sounds to me like no other French I've heard. I asked a Hispanic friend of mine once if Mexican Spanish sounded any different from his Puerto Rican Spanish, and he said it was like night and day, and the Spanish spoken in some areas of South America sounded to him at times like another language. We have common languages, but uncommon dialects!
