" I put my feet up on the desk. I could still see out the window. Why do the lights of the city, seen from a distance, appear to twinkle? When you look at them up close, they have a steady shine. It must have something to with the intervening air, with the millions of minute specks of dust swirling in it, maybe. Everything looks fixed, but it’s not; it’s moving. The desk I was resting my feet on, for instance, wasn’t solid at all but a swarm of particles so small that no human eye will ever be able to see one. The world, when you come down to it, is a scary place. And that’s not even counting the people. "
