Here's an example of small world-ishness. My sister and I had visited my dad in Abu Dhabi and on the plane home we start talking to the fellow behind us, a Saudi national. Turns out that he is going to the university that my sister just graduated from the year before (ASU Tempe), lives in the building that she lived in off campus and had lived there when she went there, and knows a whole bunch of her friends. Weird how you can live in the same building as someone and never meet them until you are half way around the world...
