One of the books we read/rowed was "How to make an apple pie and see the world". At this stage, I'm not about to make you memorize facts about different countries or anything ridiculous like that. We're learning about the world in general and try to broaden our horizons a little, introduce certain concepts and widen our vocabulary a bit.
Subconsciously, or inadvertently, you have picked up bits and pieces of information about the different countries mentioned in the stories we read. I mean, I tend to learn all kinds of things each week when we go through our different books. It is quite exhilarating :)
