Unexpected encounter

I live in Brazil with my wife and two kids - a girl and a boy. In june 2010 I travalled with my wife and my daughter (my son had not been born yet) to California. Upon arriving in Los Angeles, we took the shuttle from the rental car company in order to pick up the car we had booked. There was another couple in the shuttle and while we traveled from the terminal to the rental company site, me and my wife were chatting. By the time we arrived at the rental car company office the lady that was in the shuttle approached me and asked if we were from Brazil. I said yes and she followed asking if we were from the city of Curitiba, to which I said yes. She then told me that her brother lived in Curitiba as well, and that his name was Rick. Surprisingly her brother and I used to go to the same gym at that time and used to talk very often! She and her husband were living near the east coast of the U.S. and were travelling to L.A. on vacation. What a coincidence!
