And how we become like our parents! How their scorned advice - based, we felt in our superiority, on prejudices and muddled folk wisdom - how their opinions are subsequently borne out by our own discoveries and sense of the world, one after one. And as this happens, we realise with increasing horror that proposition which we would never have entertained before: our mothers were right!

When we love others, we naturally want to talk about them, we want to show them off, like emotional trophies. We invest them with a power to do to others what they do to us; a vain hope, as the lovers of others are rarely of much interest to us. But we listen in patience, as friends must, and as Isabel now did, refraining from comment, other than to encourage the release of the story and the attendant confession of human frailty and hope.

The problem, of course, was that people did not seem to understand the difference between right and wrong. They needed to be reminded about this, because if you left it to them to work out for themselves, they would never bother. They would just find out what was best for them, and then they would call that the right thing. That's how most people thought.

I just focus on getting the first scene right, with a few lines about the overall plot, and then the book grows organically.

I have three older sisters, so we were a reasonably large family and, in general, a happy one.

Each of us is born into our own mysteries but the mystery of another might just take us in and embrace us. And then what a sense of homecoming, of belonging!

That my philosophy of life is, as far as possible, one of enjoyment. I'm not nihilistic.
