I have had soooo much fun with this. I like to choose places opposite of eachother and say that the people are opposites. The opposite of a Brazilian? An Indonesian.

Other intriguing opposites:

Colombia/ Thailand
Argentina& Chile/ China
Spain/ New Zealand
Mongolia/ Argentina
Vietnam/ Peru



There are others. I think.
