If a Protestant gentleman accompanies a lady who is a Roman Catholic to her own church, it is an act of courtesy to offer the holy water. This he must do with the ungloved right hand.
In visiting a church for the mere purpose of seeing the edifice, one should always go at a time when there are no services being held. If people are even then found at their devotions, as is apt to be the case in Roman Catholic churches especially, the demeanor of the visitor should be respectful and subdued and his voice low, so that he may not disturb them.
INVITATION TO OPERA OR CONCERT.
A gentleman upon inviting a lady to accompany him to opera, theatre, concert or other public place of amusement, must send his invitation the previous day. The lady must reply immediately, so that if she declines, there shall yet be time for the gentleman to secure another companion.
It is the gentleman's duty to secure good seats for the entertainment, or else he or his companion may be obliged to take up with seats where they can neither see nor hear.
CONDUCT IN OPERA, THEATER OR PUBLIC HALL.
On entering the hall, theater or opera house the gentleman should walk side by side with his companion unless the aisle is too narrow, in which case he should precede her. Upon reaching the seats, he should allow her to take the inner one, assuming the outer one himself.
A gentleman should, on no account, leave the lady's side from the beginning to the close of the performance.
If it is a promenade concert or opera, the lady may be invited to promenade during the intermission. If she declines, the gentleman must retain his position by her side.
There is no obligation whatever upon a gentleman to give up his seat to a lady. On the contrary, his duty is solely to the lady whom he accompanies. He must remain beside her during the evening to converse with her between the acts, and to render the entertainment as agreeable to her as possible.
