Mark Lawson has a problem. He is writing a memoir but he's always had the habit, when writing or broadcasting, of avoiding the first person pronoun. This rather puts him at odds with modern culture where journalists and presenters are urged to use the one-letter vertical word. Bloggers, Vloggers and Tweeters lay their lives on-line, and autobiography is an ever more crowded literary form. So, in his series of One to One, Mark takes the opportunity to discuss self-revelation with artists who - in various ways - have taken themselves as their subject matter. Here he talks to writer and novelist Rachel Cusk who found herself branded, 'the worst mother in Britain' for writing candidly about her experience of motherhood.
