H. said something funny

My sister lives in Canada and we've been talking about Canada. Last week when I was singing Fifty Nifty United States, H. said, "Canada is just part of America. How come you didn't say Canada?" SO, we talking about North America and that Canada is on our continent, but not one of the 50 states. I thought the wholething was so funny because Canadians, while visiting Eastern Europe always got so offended when they were told that they were Americans. I guess it is funnier to me, but there, I shared it.
