Quote from : Memoirs of a Geisha Book

Here's the thing: this eel spends its entire life trying to find a home, and what do you think women have inside them? Caves, where the eels like to live...when they find a cave they like, the wriggle around inside it for a while to be sure that...well, to be sure it's a nice cave, I suppose. And when they've made up their minds that it's comfortable, they mark the cave as their territory...by spitting.
