Upon entering a theater or concert hall a few moments before the curtain is drawn, one becomes immediately conscious of the gentle buzz of voices throughout the audience. While it is entirely permissible to carry on a conversation before the play begins, it is most offensive to those who are sitting near for one to act in a noisy, conspicuous manner. Low tones are a mark of cultivation. As a matter of fact, loud noise of any kind is an exhibition of thoughtlessness, and it can be so easily avoided by a little caution.

At a theater party, when there are several men and women in the party, the men may take advantage of the intermission to leave their places for a few moments. But they must not indulge in this privilege more than once during a performance, if they wish to be polite and considerate to the ladies. And they should not go without excusing themselves to the ladles whom they are escorting.
When a young man and woman are together, it is the height of ill-breeding for him to leave her alone during intermission.
