yihao,
I love to talk to people on the plane and am always very disappointed when I get stuck next to a boring old stick-in-the-mud. I have had some truly memorable conversations on planes, boats and trains and enjoyed myself tremendously.
I have even made a few friends on the plane whom I see regularly when I am in their town or they are in mine. For me it is the people I meet that make travel exciting, as much as the places I see.Certainly was true last week in Hawaii.
