The next thing I picked up to read was "A Temporary Matter," a short story from Jhumpa Lahiri's collection, Interpreter of Maladies. The premise of the story revolved around a scheduled blackout. In order to repair local power lines, a young couple would be without power starting from 8:00 p.m. for exactly one hour. The similarity of the couple's situation to Earth Hour struck me (although unlike Earth Hour, this blackout would be repeated throughout the week until the lines were repaired).
For the characters in "A Temporary Matter," these scheduled hours of darkness were the time when they came to terms with a tragic event that had damaged their relationship. Being alone in the dark together, lighting candles, telling stories, reconnected them. Now, the morning after Earth Hour, we read that the globally scheduled hour of darkness not only represented environmental responsibility and hope for the future, but that it brought people together on both a global and local level.
Why is it so much easier for human beings to connect in the dark, their meeting lit only by flickering candles? Something about the darkness makes us shed just enough of our individual defenses to connect with others. Perhaps our reaction is simply a throwback to our primitive past, huddled in the darkness with only a fire and our companions for warmth. And certainly part of the answer is that when we are cut off from the distractions of our modern lives, and have nothing to pay attention to but the people around us, we suddenly realize that they're there.
