There could have been nothing very free or joyful about talking according to a program as the ladies of the eighteenth-century salons were more or less inclined.

Good conversation runs like water; nothing is foreign to it.

"Farming is such an unintellectual subject," I heard a critical young woman say to her husband, whose tastes were bucolic.

The young woman did not realize that one of the masterpieces of the greatest of the world's writers was on farming--most practical farming, too! That which relates to the life of each, interests each, concerns each--that is the material for conversation, if it is to be enjoyable or productive.
One of a woman's real difficulties in creating a free-speaking household is her natural tendency to regard opinions as personal.

To differ is something she finds it difficult to tolerate.
