“Have you tried reading a book in bed?” I asked.
“Of course I have,” Sally has a way of belittling anything you say, “but it doesn't work. That's the one time I don't fall asleep, but I'm too tired to take anything in.”
“Sounds horrible,” I said. I meant it but I was glad we’d reached the office and I could let Sally whinge to someone else. “Catch you later.” I wondered over towards the kettle wondering how a simple, how are you getting on with the latest Jo Nesbo book? had led to a detailed insight into Sally’s sleeping patterns.
