Oh yes, I guess there is. And there's always something autobiographical in my own work - here is the simple irritation of me as a wife when Jamie's insistant at something when I'm busy, damn it, and his catastrophising when he's stressed which stresses me out - but also, him kissing my elbows when we first made love. The rest is fiction - I've never ever been to Paris. So yes, there's a crossover, always.
