People stick hearts on Valentine's cards and get married in white dresses and give each other flowers. They think love is every-thing going right. That's not love. That's self-indulgence. That's good luck. Love is when you walk into the burning building. Love is when the person who means most to you in the world is breathing through a mask and pissing in a bag. Love is when they no longer know your name.

He is the only man she has ever loved, and he has dumped her like ballast. She needs to find an explanation that does not make her a fool and him an animal, but every thought of him is a knife turning in the wound love made.

Water purling between the rocks, weed under the surface like green hair in the wind.

Snow... blots and softens the top of every object like ice on a plum pudding. Hedges, telegraph wires, cars, postboxes, recycling bins. The world is losing its edges. Look upwards and it seems as if the stars themselves are being poured from the sky and turn out not to be vast and fiery globes after all but tiny, frozen things which melt in the palm of your hand.

Melissa popped open the clattery little Rotring tin. Pencils, putty rubber, scalpel. She sharpened a 3B, letting the curly shavings fall into the wicker bin, then paused for a few seconds, finding a little place of stillness before starting to draw the flowers. Art didn't count at school because it didn't get you into law or banking or medicine. It was just a fluffy thing stuck to the side of Design and Technology, a free A level for kids who could do it, like a second language, but she loved charcoal and really good gouache, she loved rolling sticky black ink on to a lino plate and heaving on the big black arm of the Cope press, the quiet and those big white walls.

Then he asked if I didn__ like things changing. And I said I wouldn__ mind things changing if I became an astronaut, for example, which is one of the biggest changes you can imagine, apart from becoming a girl or dying.

Prime numbers are useful for writing codes and in America they are classed as Military Material and if you find one over 100 digits you have to tell the CIA and they buy it off you for $10,000. But it would not be a very good way of making a living.

I find people confusing.

Lots of things are mystries. But that doesn't mean there isn't an answer to them. It's just that scientists haven't found the answer yet.

... why I like timetables, because they make sure I don't get lost in time.

I like poetry when I don't quite understand why I like it. Poetry isn't just a question of wrapping something up and giving it to someone else to unwrap. It just doesn't work like that.

I am really interested in eccentric minds. It's rather like being fascinated by how cars work. It's really boring if your car works all the time. But as soon as something happens, you get the bonnet up. If someone has an abnormal or dysfunctional state of mind, you get the bonnet up.

Use your imagination, and you'll see that even the most narrow, humdrum lives are infinite in scope if you examine them with enough care.

Things can be funny when people are uneasy. It softens them up and stops them falling asleep on the sofa. I like those moments where people half-smile and half-wince.

And when you look at the sky you know you are looking at stars which are hundreds and thousands of light-years away from you. And some of the stars don__ even exist anymore because their light has taken so long to get to us that they are already dead, or they have exploded and collapsed into red dwarfs. And that makes you seem very small, and if you have difficult things in you life it is nice to think that they are what is called negligible, which means they are so small you don__ have to take them into account when you are calculating something.

Reading is a conversation. All books talk. But a good book listens as well.

Siobhan said that when you are writing a book you have to include some descriptions of things. I said that I could take photographs and put them in the book. But she said the idea of a book was to describe things using words so that people could read them and make a picture in their own head.
