Swans a’swimming

Two boys set out at dawn on a hike into the woods.

They can around a hill and discovered a small stream-fed lake they had never seen before.  Mist was rising from the lake, the sun rose, and then gliding silently into their view they saw swans.

The one boy was awestruck.

The other complained, “where are they going?  There is nothing in this lake.  This is pointless.  Why aren’t they all in a line?  Why aren’t they forming a pattern?”
