But Hi & Lois' Chip makes this point, which is valid... there are more nations in the world now than ever before, and thus so much more to know/learn. And what with the interwebs one doesn't need to memorize geography, right? ..... but that's different than being utterly oblivious to one's own geopolitical location, much less immediate neighbors. Or maybe such people merely instinctively reject the divisive artificial political constructs of borders and know in their hearts that we are all simply fellow travelers on this Spaceship Earth. Yes? ... Maybe not.
