I believe there was a word for this kind of realization, but I forgot it and can’t find it anywhere. (edit: it’s sonder)
So you’re sitting in the train, heading to work or something. Some guy sits in front of you. He has his own set of friends, family members, colleagues, acquaintances, and so on. And all those people have their own connections as well. Within only a few iterations, you’re spanning pretty much the entire human population on earth. There was a study once, calculating how many people are needed to link back to oneself. The average number was five if I recall correctly, but I’m not entirely sure.
But that’s a really small number, don’t you think? Yeah, but the amount of people we come in contact with in our lives in mind-boggling. It’s kind of… depressing, in a way, when you realize all those people have their own worlds they live in, with their own problems, pleasures, experiences, everything. It feels weird because you always only see things from one perspective, yours, and so the others are kind of blurred out. You know your friend is a thinking, living being, but move that to a much larger scale. All these people you’ll never know, they have complicated lives as well.
Just think about it for a second. Sit there, think, and report your thoughts and feelings in the comments.
