Fear and anxiety are great motivators for me.

She shouldn't speak her thoughts; nothing good ever came of speaking your thoughts.

I can't believe it's actually happening. This is independent adulthood, this is what it feels like. Shouldn't there be some sort of ritual? In certain remote African tribes there'd be some incredible four day rites of passage ceremony involving tattooing and potent hallucinogenic drugs extracted from tree-frogs, and village elders smearing my body with monkey blood, but here,rites of passage is all about three new pairs of pants and stuffing your duvet in a bin-liner.

For the best part of my childhood I visited the local library three or four times a week, hunching in the stacks on a foam rubber stool and devouring children's fiction, classics, salacious thrillers, horror and sci-fi, books about cinema and origami and natural history, to the point where my parents encouraged me to read a little less.

Occasionally, very occasionally, say at four o’clock in the afternoon on a wet Sunday, she feels panic-stricken and almost breathless with loneliness. Once or twice she has been known to pick up the phone to check that it isn’t broken. Sometimes she thinks how nice it would be to be woken by a call in the night: ‘get in a taxi now’ or ‘I need to see you, we need to talk’. But at the best of times she feels like a character in a Muriel Spark novel – independent, bookish, sharp-minded, secretly romantic.

I think I became a writer because I used to write letters to my friends, and I used to love writing them. I loved the idea that you can put marks on a page and send it off, and two days later, someone laughs somewhere else in the world.
