Quote from : Norwegian Wood Book

Reiko set the ball on the ground and patted my knee. "Look," she said, "I'm not telling you to stop sleeping with girls. If you're O.K. with that, then it's OK. It's your life after all, it's something _you_ have to decide. All I'm saying is that you shouldn't use yourself up in some unnatural form. Do you see what I'm getting at? It would be such a waste. The years nineteen and twenty are a crucial stage in the maturation of character, and if you allow yourself to become warped when you're that age, it will cause you pain when you're older. It's true. So think carefully. If you want to take care of Naoko, take care of yourself too." I said I would think about it.
