"She is omnipotent. She can conjure up an army of parkour chimney sweep ninjas! But she also has to come and go with the weather, and where there is technology, if you like, it does not always do what it should. It plays up. The umbrella handle is a bit shitty with her. The toys don't always clean themselves up at her command." I always like Schulze on Mary Poppins, and whilst it's quotable, it's probably not the most representative quote of this marvellous article. The main reason I use it is this article, more than many I've read, explains what being in a room with Jack at work is like. It's also lovely to see all the threads, some of which I saw beginning, come together. Good photos, too, of what work looks like.
