ABSTRACT
Sharing is the commonest of behavior. All of us share with others. As scientists we share our thoughts with each other, as well as the joys and griefs of discovery. Husbands share their thoughts and possessions with wives, wives with husbands, and both share with their children. Children share. And since we know that they do share, we may ask when does sharing start. With whom and what do they share? What is the nature of the first sharing?
