After being driven around Europe for six months as a child, I developed quite an obsession with things geographical: capital cities, currencies, languages and especially flags. One of the local banks put out a poster every year or two showing all the flags of the world and I adored this poster. Yes, I was a geek.
But apparently geeks breed geeks. This photo is not a set up - the small boy was left to his own devices for a minute or two and flipped over the pages in this big standing-up book thing to the page full of flags. However, given that he is not even two yet, I should say he's not exactly pointing to particular country's flags on demand. What he is mostly interested in is the flags which feature moons (a surprising number, actually - and the background is explained in Wikipedia's bit on Islamic flags) because he's going through a moon-obsession phase. I did manage to briefly distract him with flags featuring stars (also a large number) but the moons won over. Pakistan was a particular favourite.
But I'm hoping that his interest in flags will remain. And grow. And he'll be begging me to take him to some distant country or other and I'll just have to go travelling again, you know, for the sake of his development.
