Life covers a full circle.. At first one is ignorant.. So he keeps quiet.. Then he starts learning.. Simultaneously he starts talking.. he starts talking of his victories and failures, travails and experiments, his ups and downs.. The world listens first.. maybe because it is hearing a fresh noise.. But as the litany progresses, the whole world except the speaker gets bored.. One is tolerated for a time and then is ignored completely.. If he is wise, he stops talking even when he has not become intolerable for others. Otherwise he is asked to shut up. Finally he is forced to shut up.. Anyway he has to keep quiet. So he keeps quiet.. It is a journey from silence to silence..
