America is 2 continents (North and South). So when I hear that a country calls itself by the name of 2 continents, it sounds as if it wants to look really big.
Maybe I'm wrong, but that is my impression when they say, "here in America"........
For example if you go to China, and say to the Chineese that America is beautiful, well what would they think? Would they think of The US or would they think of the continent as beautiful?
Go to another country and say, that you live in America. They would say to themselves, well where in America?
So that's my reasoning.....
