“What do I like about math? , When I've got figures in front of me, it relaxes me. Kind of like, everything fits where it belongs.”

“Math is like water. It has a lot of difficult theories, of course, but its basic logic is very simple. Just as water flows from high to low over the shortest possible distance, figures can only flow in one direction. You just have to keep your eye on them for the route to reveal itself. That’s all it takes. You don’t have to do a thing. Just concentrate your attention and keep your eyes open, and the figures make everything clear to you. In this whole, wide world, the only thing that treats me so kindly is math.”

“Tell me how you could say such a thing, she said, staring down at the ground beneath her feet. You're not telling me anything I don't know already. 'Relax your body, and the rest of you will lighten up.' What's the point of saying that to me? If I relaxed my body now, I'd fall apart. I've always lived like this, and it's the only way I know how to go on living. If I relaxed for a second, I'd never find my way back. I'd go to pieces, and the pieces would be blown away. Why can't you see that? How can you talk about watching over me if you can't see that?”

“I don’t know why I’m so crazy about cats. I like how they are soft and warm, and individualistic, kind of like me.”

“You mean, if you knew me better, you'd force stuff on me like everybody else?Toru: It's possible," I said. "That's how people live in the real world: forcing stuff on each other.Midori: You wouldn't do that. I can tell. I'm an expert when it comes to forcing stuff and having stuff forced on you. You're just not that type. That's why I can relax with you. Do you have any idea how many people there are in the world who like to force stuff on people and have stuff forced on them? Tons! And then they make a big fuss, like, 'I forced her,' 'You forced me'! That's what they like. But I don't like it. I just do it 'cause I have to.”

“I'm struck by how pitiful and pointless this little container called me is, what a lame, shabby being I am. I feel like everything I've ever done in life has been a total waste.”

“I've always done whatever I felt like doing in life. People may try to stop me, and convince me I'm wrong, but I won't change.”
