Its happened to me at least 4 times (and we travel a lot). Once I was in Paris touring the castles (overseas study program) and ran into someone from home. Another time my family and I were traveling around California. One morning we walked out our room and at the same time, right next door, out walked my brother's friend and his family! Another time we arrived at the airport in Hawaii and ran into our neighbor. Then on the flight home, we ran into our other neighbor on the plane!
That all happen when we lived in Chicago. Now we are in SC. I moved to Hilton Head when my dad retired there. Suddenly we keep running into friends from back home who now live there too (a family down the street, a former neighbor, former swim teammate of mine, and get this, a man whom with my dad used to play toy soldiers!). It's a small world after all!
