Ralph Waldo Emerson said this quote

“ In good company there is never such discourse between two, across the table, as takes place when you leave them alone. In good company, the individuals merge their egotism into a social soul exactly coextensive with the several consciousnesses there present. No partialities of friend to friend, no fondnesses of brother to sister, of wife to husband, are there pertinent, but quite otherwise. Only he may then speak who can sail on the common thought of the party, and not poorly limited to his own. Now this convention, which good sense demands, destroys the high freedom of great conversation, which requires an absolute running of two souls into one. ”
