Let us be guests in one another’s house, with a deferential “No” and courteous “Yes.” Let us take care to hide our foolish moods behind a certain show of cheerfulness. Let us avoid all sullen silences. We should find fresh and sprightly things to say. I must be fearful lest you find me dull, and you must dread to bore me any way. Let us knock gently at each other’s heart, glad of a chance to look within—and yet let us remember that to force one’s way is the unpardoned breach of etiquette. So we shall be host and hostess, until all need for entertainment ends. We shall be lovers when the last door shuts. But what is better still, we shall be friends.
