In addition to the obvious points, I was struck by how well the Palestinians were dressed (note: it's a warm climate). No evidence of grinding poverty. And let me share a personal story: I was once touring the Negev with my parents and we happened upon a bucolic scene of a Bedouin boy tending a flock of sheep. We stopped to take a picture. The boy, obviously misconstruing our desires, obligingly picked up a rock and posed for us, as if he were about to throw it. Now where could he have learned to do that?
