“I would never wait two minutes in a store without looking at my phone or reading a book. The idea of not filling every minute with stimulation panicked me, and I found it weird when I saw other people not doing it. On long train or bus journeys, whenever I would see somebody just sit there for six hours, doing nothing but stare out of the window, I would feel an urge to lean over to them and say, “I’m sorry to disturb you. It’s none of my business, but I just wanted to check— you do realize that you have a limited amount of time in which to be alive, and the clock counting down toward death is constantly ticking, and you’ll never get back these six hours you are spending doing nothing at all? And when you are dead, you’ll be dead forever? You know that, right?”
