This is true. Do you ever look at a huge gathering of people and think, "Man, we are just a bunch of disgusting little breeding bugs."? I do, sometimes. When you look at all those people, they seem no more discernable as individuals than when you look down at all the ants scampering around an anthill.
I get the same feeling in a mall or at Wal-Mart too, actually. Maybe I think too much.
