Excerpt from Kokoro by Natsume Sōseki.

We walked back in silence

. Then after quite some time, Sensei spoke.
“I’ve done wrong. I left home angry, and my wife will be worrying about me. Women are to be pitied, you know. My wife has not a soul except me to turn to.”

The route back to Sensei’s house passed very near my lodgings. But when we reached that point, it did not feel right to part with him. “Shall I see you to your house?” I asked.
He raised a quick defensive hand. “It’s late. Off you go. I must be off too, for my wife’s sake.”
“For my wife’s sake”—these words warmed my heart. Thanks to them, I slept in peace that night, and they stayed with me for a long time to come.

Sensei once confided to me, “I have only ever known one woman in my life. No one besides my wife has really ever appealed to me as a woman. And likewise for her, I am the only man.
