For the folks that have met me I am not tiny and frequently find myself sitting between two even larger people. Elbow hockey all the way. Having sat next to grossly obese folks I realize a couple of things, they arnt any more comfortable than you are. Unless international almost no hops are over 4 hrs. I can sit motionless for 4 hrs if I have to. As Carlin sez, this is a bus yer a waitress so get me a drink.
thanx,
bill
