It is only when you watch the dense mass of thousands of ants crowded together around the Hill blackening the ground that you begin to see the whole beast and now you observe it thinking planning calculating. It is an intelligence a kind of live computer with crawling bits for its wits.
Spare a thought for the poor introverts among us. In a world of party animals and glad-handers they're the ones who stand by the punch bowl. In a world of mixers and pub crawls they prefer to stay home with a book. Everywhere around them cell phones ring and e-mails chime and they just want a little quiet.
