“Places remained and time flowed through them like wind through the grass. Right now. This was the future turning into the past. One thing becoming another. Like a flame on the end of a match. Wood turning into smoke. If only we could burn brighter. A barn roaring in the night.”

“It exasperated her sometimes. The way men could be so sure of themselves. They put words together like sheds or shelves and you could stand on them they were so solid. And those feelings which overwhelmed you in the small hours turned to smoke.”

“When people die they are sometimes put into coffins, which means that they don't mix with the earth for a very long time until the wood of the coffin rots. But Mother was cremated. This means that she was put into a coffin and burned and ground up and turned into ash and smoke. I do not know what happens to the ash and I couldn't ask at the creamatorium because I didn't go to the funeral. But the smoke goes out of the chimney and into the air and sometimes I look up and I think that there are molecules of Mother up there, or in clouds over Africa or the Antarctic, or coming down as rain in the rain forests in Brazil, or snow somewhere.”

“People think that alien spaceships would be solid and made of metal and have lights all over them and move slowly through the sky because that is how we would build a spaceship if we were able to build one that big. But aliens, if they exist, would probably be very different from us. They might look like big slugs, or be flat like reflections. Or they might be bigger than planets. Or they might not have bodies at all. They might just be information, like in a computer. And their spaceships might look like clouds, or be made up of unconnected objects like dust or leaves.”

“He had always thought of solitary diners as sad. But now that he was the solitary diner, he felt rather superior. On account of the book, mostly. Learning something while everyone else was wasting time. Like working at night.”

“I think prime numbers are like life. They are very logical but you could never work out the rules, even if you spent all your time thinking about them”
