It was all very tense and thrilling.

"Shhhh," I said to my toddler, George, to indicate that this was important, and maybe he'd like to go and quietly read his tractor book.

George put his own finger to his lips, blew a raspberry and fell about laughing. I put him on the kitchen floor and gave him two arrowroot biscuits. He looked at me suspiciously and stuffed both biscuits in his mouth before I changed my mind. The phone call began well. The first producer said lovely things about my book.
