Friendship is a precious thing, Sayuri. One mustn't throw it away.

If a few minutes of suffering could make me so angry, what would years of it do? Even a stone can be worn down with enough rain.

If those sorts of moments would be the only pleasure life offered me, I'd be better off shutting out that one brilliant source of light to let my eyes begin to adjust to the darkness.

Never give up; for even rivers someday wash dams away.

Finally the homeless eel marked its territory, I suppose, and the Doctor lay heavily upon me, moist with sweat.

In the instant before the door opened, I could almost sense my life expanding just like a river whose waters have begun to swell; for I had never before taken such a drastic step to change the course of my own future. I was like a child tiptoeing along a precipice overlooking the sea. And yet somehow I hadn't imagined a great wave might come and strike me there, and wash everything away.

Friendship is a precious thing, Sayuri. One mustn't throw it away.
