Many years ago on a street in my neighborhood was a pack of dogs. They would chase every car that would pass by. Barking and chasing until the car went past. Sometimes there were a few. Other times they were joined by friends from neighborhoods far far away. They would tire themselves out and triumphantly return back to the pack, perhaps thinking that they scared the car away.
No one knew what they wanted. One time we stopped our car and the poor animal halted dead in its tracks, its bark fading into a puppy like squeal, and scared out of its wits it retreated in its own tracks.
Then one day they just disappeared. Perhaps they were trying to say something.
