So many of the scenes just write themselves
Jack trudging through the rain, clutching son's hand, as she goes from shop to shop to ask for work, each time being dismissed with a wordless shaking of the head.
Jack sadly unscrewing light bulbs and unplugging the fridge, as sb, dressed in faded, too small clothing lisps 'bwead an jam mama wan bwead an jam'
Jack laboriously typing out her hunger hurts on her trusty Nokia.
Jack being discovered and making her first trip to London. Looking round wide eyed in amazement - 'Lunnon, ain't never been to Lunnon before!, couldn't never afford it. Lummee! It's so big and noisy!
Jack being taken out to eat by her publisher, hilarity ensues when she plays knees up mother brown on the posh piano.
