Last week, in less than 48 hours, I ran into 4 friends/ acquaintances that I don't normally cross paths with. One showed up in my living room -a friend of my roommate, unbeknownst to me. I stood next to two of them on the metro, on separate occasions. And another I saw from across the street and we said hello in the middle of the crosswalk. Did I mention that an estimated 8,851,080 people live in the DF?
Big city. Small world.
