“It’s beautiful, it’s paleolithic, it’s monumental, it’s dignified, it will never, ever let me down. It’s not going anywhere: it’s a metaphor for what I prefer to live with. I prefer to be single, doing everything I want to do and how I want to do it. … If I feel really low – anything from ‘I shouldn’t have said that’ to ‘I don’t feel very well’, to ‘I feel a bit lonely’ – I think about the stone and it actually makes me feel better.”
