I used to look at a map of the world and think that it was only half of the world, and that when I flipped over the map, the other half of the world should be there. I would demand "but where is the other half of the world?" and become very distressed that grownups apparently weren't alarmed that half of the world was missing, which made me think that they were being brainwashed and I was the only one who knew that some greater power was trying to hoodwink us, or else the other half of the world didn't show up on the map because it wasn't discovered yet. I swore to become an explorer and find the other half of the world when I grew up. And yup -- I love traveling the world, though I know all the major landmasses are where they are supposed to be.
