Leader of the Pack

At first -  there was nothing. A river. A riverbank. An uninspiring ky of endless grey. Everywhere I looked - up down and under and behind - there was no life...no color. Nothing.

And then - it happened. Out of nowhere they appeared. First one...and then the other three. One swooped up and into the sky...the others followed. That same one - then - dipped down..and then up and then down and then up again. All in ther right place and in their just right line - the others did exactly the same.

I wondered about what it was he was doing? What game -  perhaps -  he was playing? Was he trying to get away and ahead of his pack? Was he trying to disappear from sight? Out of view?

Or - was he leading....knowing that the others would follow?
