At the opera it is customary for ladies and gentlemen to leave their seats, and promenade in the lobbies or foyer of the house during the intervals between the acts. The gentleman should always invite the lady to do so. Should she decline, he is bound to remain with her.
A gentleman accompanying a lady is not bound to give up his seat to another lady. His duty is solely to the lady he accompanies. He cannot tell at what moment she may need his services, and must remain where she can command them.
It is rude to whisper or talk during a performance. It is discourteous to the performers, and annoying to those of the audience around you, who desire to enjoy the entertainment.
To seek to draw attention to yourself at a place of amusement is simply vulgar.
It is in especial bad taste for lovers to indulge in any affectionate demonstrations at such places.
A gentleman must see that the lady accompanying him is provided with a programme. If at the opera, he must also provide her with a libretto.
Applause is the just due of the deserving actor, and should be given liberally. Applaud by clapping the hands, and not by stamping or kicking with the feet.
Upon escorting the lady back to her home, the gentleman should ask permission to call upon her the next day, which request she should grant. She should, in her own sweet way, cause him to feel that he has conferred a genuine pleasure upon her by his invitation.
A gentleman who can afford it should always provide a carriage on such occasions. If his means do not permit this, he should not embarrass himself by assuming the expense. If the evening be stormy, he should not expect the lady to venture out without a carriage.
A gentleman should call at the lady's house in full time to allow them to reach their destination before the commencement of the entertainment.
