I do not think it is possible to feel empathy for 7 billion people. I know it is not possible to mourn the ~400,000 souls we lose to death every day on this planet earth. In a city like New York, it is not even reasonable to say Hi to everyone you pass on the street. Forget New York, it wasn’t reasonable to say Hi to everyone I passed at XOXO. There are too many humans. Boundaries must be drawn. Who are our friends, who is in the community, who gets to count. The boundaries can be drawn wider or narrower, and with more or less care. But the starting points of those boundaries are necessarily accidents of history, and history is pretty messed up.
