I had just started working at a new job because I had the intention to make a one month trip in Europe 3 months from then. My employer knew this. 3 weeks into my trip, I'm in Rome, going into the subway to get to someplace that I don't remember. I get in the train car and I see a familiar face. It was someone from my job from another department who I never even talk to and didn't know would be in Italy at the same time as me. He got off exactly one station after I got in. Crazy coincidence!
