I grew up in a small town of about 20k people. 10 years later I met a man on a squatted farm in the countryside 30 Km outside of Barcelona. He was from a small village in Belgium, and living in Barcelona, but visiting this farm to learn to brew beer. I was visiting this farm as I traveled by, and only there for one day. After talking throughout the day, I told him the town I came from, and it turns out that he did an exchange student program and the same highschool I was attending, at the same time. We were different years and did not know eachother, but shared several mutual friends.
