Hive account@arminnavabi made very valid point there, Along with this there are Regional Dialect, that is undocumented part of the culture, there are "n" number of cultures and populations around world, we are yet to encounter. Some of the findings are very magical, like the island of Fiji (its an independent country) is 11,597 km away from India and still have very similar tradition and languages, with some variations. Same can be said with Arab countries, there a small variations but at core they are all same. Am I right ???
