I sang nursery rhymes to toddler A under the watch of her adoring parents J and N. Then I set off to London to do some work.

On arrival at the British Library GW and I were very confused by the new layout of the building. There were no ‘up’ escalators, and the Humanities Reading Room had vanished. I had a further problem of my own: I had left my MacBook Air at J’s house, so couldn’t get on with the work that I had planned.
