Where did love begin?What human being looked at another and saw in their face the forests and the sea? Was there a day, exhausted and weary,dragging home food, arms cut and scarred, that you saw yellow flowers and, not knowing what you did, picked them because I love you? In the fossil record of our existence, there is no trace of love. You cannot find it held in the earth's crust, waiting to be discovered. The long bones of our ancestors show nothing of their hearts.

If Tolstoy had known this, would he have recognised the terrible untruth at the beginning of Anna Karenina? 'All happy families are alike; every unhappy family is unhappy in its own particular way.' In fact it's the other way around. Happiness is a specific. Misery is a generalisation. People usually know exactly why they are happy. They very rarely know why they are miserable.

London is a small place, and it is very incestuous. People know where you live. Everybody is sort of on top of each other.
