Have you ever noticed anyone staring out a train window when you're inside a tunnel? I noticed someone doing that today. At first I thought it was weird, but before long I remembered that I do that from time to time. There is nothing but darkness outside the window, save the occasional light hanging on the wall of the tunnel.
So what are we, the people who like to stare out at nothing, observing?
I must admit that I sometimes do it to observe the people in the carriage with me, but in a way that's not so obvious.
But the times when we just stare out into the black tunnel, what's so interesting?
