It is impossible from head-nodders to learn the subject of their gossip. But gossip they do, nod they do, smile and frown and clap they do like starlings at early dawn; they flap, they rustle, they cling together and rise from the grasses and fly together, this way and that, seeking the leader whose randomness fails them.
At sundown the murmeration ceases and together they rustle, they rhyme with the rhythm of the restless till darkness overcomes. Tomorrow they will rise again and like starlings everywhere they will rise as one and heads will nod and the bloated carcasses of their forgotten comrades will add nourishment to the earth and one or two will say do you remember whatsisname. Oh yes comes the answer, he was always coming up with strange, new ideas.
And the head-nodders bestow their final, limited approval in measured doses and their world continues at break neck speed.
