Why does Sanji call Nami "Nami-san"? I know san confers respect and all that, but doesn't it also create a kind of polite distance between people? So, if Sanji loves (or rather, lusts after) Nami, why wouldn't he use "Nami-chan" to sound more familiar and close? He says "Vivi-chan," so I don't understand why Nami is different...
