Every now and again the feeling will rise up, a little prick at the back of my mind to remind me of the times we live in. I find myself taking a morbid outlook at my surroundings when the feeling arises. I think of tactical vulnerabilities. I look around the train, or the station, or I gaze at the skyline and picture the scene becoming mangled and grotesque in an instant. But just as quickly as the feeling comes on, away it goes. It would be impossible to live in this city from day to day if I were to think about the inevitable. After all, the odds are with me. There are eight million people living in this city, with millions more visiting it every day for work or play. An explosion tearing its way through a bus, a subway train, or a crowded movie theater represents a grim lottery that only a few will lose. It’s the knowledge, that “it’s only a matter of time” mentality which becomes a strain. So the inevitable explosion, the inevitable carnage, the fact that this grim lottery is being played out despite the participant’s unwillingness to play, is ignored, otherwise I would think myself a fool every time I walked down the steps to the subway platform.
