She was an easy artist to be with - very easy to talk to. I brought Miles Davis CDs to listen to, and his soundtrack to the movie Siesta was one she hadn't heard before, so that played while she worked. I'm a curious person, so we talked about lots of things.
I sat for her four times. I think she took some photos, but she's a very quick worker. When you're sitting, you're at your leisure to a degree. How often do you have a chance to sit down? Sitting down and me - it's an oxymoron!
I am ebullient and full of brio, full of enthusiasm - but the portrait is rather melancholy. She has found a darker side to me - I think of myself as more mischievous, a comedian, whereas this is a dark, mysterious pose. But this is how she interpreted me. When I go to the NPG I am always surprised that people recognise it as me. My family love it - they tell me that I don't see myself when I am angry or passionate, so they think this is a totally honest picture.
This is a watercolour and I love the medium. Watercolour is schizophrenic - it makes you think of someone sitting outside painting flowers, but it's so fast and immediate, and doesn't have to be wishy-washy women's institute at all. So I've learnt to respect watercolour - and I love it for its speed.
There's a phrase that says the only two ways you can see in life is if you're an artist or a golfer. There is magic when artists look at you, trying to fix a pose - it's like alchemy - they looking at the light, seeing it as no one else does. I felt almost as if I had no right to say anything when Sara started my portrait. I am quite timid when I'm in the company of artists - I think they have magic in them and I don't know how to interpret it - I'm incredibly respectful of artists.
When someone is painting you it's very intense and intimate. When you know someone is looking at you, it's quite unnerving. But it's also intriguing.
