At my parents' place the other day, I spotted a compass lying around. My 5yo is very much into geography at the moment, so I told him what it was and he surprised me with his knowledge of the existance of the north and south poles. He's always asking me about places and whether they're in Australia or not.
Suddenly he said "Dad, do you know what the capital of Sebastian is?"
I struggled to identify the place and said "no, what it is it?"
