It was a late day at the office. Which didn’t mean I was there until the wee hours, only an hour and a half later than usual, just long enough to label, transfer and prune some MP3 files that had been filling up my voice recorder.

My attention had been riveted by the screen for a couple hours, that and my inner ear, where voices from interviews I conducted months ago replayed through an earphone. It’s a strange thing, listening to voices heard only once and trying to figure out who they are. It was an interior exercise, a journey into memory, aided by last year’s day planner and typed notes.

But back to the matter at hand, which was the long day, the tedious task, and then, finally, completion. I clicked off my computer, packed up my things — and only when I stood up to grab my coat did I look out the window.

And there, spread out before me, was a magical sight. Offices that are drab brown and inscrutable in daylight were all lit up at night. What was normally invisible was suddenly seen. I marveled at the lights and the reflections. I marveled also at the comfort they brought. And that’s when it occurred to me, something I know but too often forget — that we’re never alone in our toil. Even when we think we are, there are countless others who are close by, working along beside us.
