As soon as I began, it seemed impossible to write fast enough - I wrote faster than I would write a letter - two thousand to three thousand words in a morning, and I cannot help it.
I know we will look back on this and think how odd it was we were championing the rights of lone mothers to bring up their children on benefit.
I love that there's a beginning, middle and end to a film and you can craft what the whole journey is going to look like.
