“Our heads are the last bastions of privacy”

MIDNIGHT, in bed. I’m random-googling on my laptop, while my husband turns the pages of his book with peevish flicks and martyred air.

He casts his book aside. “You’re breaking the no technology in bed rule,” he says. “And you were the one who introduced it. You said technology winds your brain up late at night, when it should be winding down.”

“Look,” I say, turning my laptop round, brain buzzing, “look at my Recent History.”
