Someone told me that he taught English at Osaka (大阪) for 5 years today. When I heard of Osaka, I thought, which place is that? It sounds so familiar and yet I don't know which place it is. So I stupidly asked whether it is a city or a quiet town. It turns out, Osaka is the second biggest city in Japan :P
