I look out my window at hundreds of tiny cars as my plane descends into Denver. There are so many people in the world. I get predictably overwhelmed by this thought whenever I am at a baseball stadium, a concert, or looking down at a city from the sky.
There are millions and billions of people, everywhere. I share personal histories with a few of them because we happened to be at the same place at the same time for one fleeting, overlapping moment in our lives.
