'We’re sitting on high stools at Kelly’s kitchen bench. She’s got one leg tucked beneath her, yogi style, the other dangling far from the floor. She’s tiny. The kitchen is white and beautiful. There are toys tucked away in open shelves and in the background we listen to the rumblings of the washing machine. Kelly’s an old friend, but we haven’t seen each other for a while, in the way that sometimes happens when people have young children.' (Introduction)
