A good read. But. to be quite honest, after growing up in the age of UFO sightings with nothing to show for it, I'm bored with it all. I mean, let's face it, if alien space ships hovered over every city and did nothing for, say, decades, what would we do? We'd find out that they were impenetrable, were not communicating with us, not threatening in any way, and we'd go back to living our lives as though those ships weren't even there. Until the aliens start talking to us then we are nothing more than helpless observers.
