When I was little, my sister had a globe on which the states of the U.S. and those of Australia were shown in different colors, although elsewhere on that globe, different colors indicated different countries. I had already learned at the time that the U.S. was all one country. But for a long time thereafter, I thought that the states of Australia were all separate countries.
