MISCELLANEOUS.
WHEN you are walking with a lady who has your arm, be careful to keep step with her, and do not force her to take long, unladylike steps, or trot beside you with two steps to one of yours, by keeping your usual manly stride.
Never allow a lady, with whom you are walking, to carry a bundle, shawl, or bag, unless both your hands are already occupied in her service.
When you attend a wedding or bridal reception, it is the bridegroom whom you are to congratulate, offering to the bride your wishes for her future happiness, but not congratulation. If you you are acquainted with the bridegroom, but not with the bride, speak to him first, and he will introduce you to his bride, but in any other case, you must speak first to the bride, then to the bridegroom, then the bridesmaids, if you have any previous acquaintance with them, then to the parents and family of the bride, and after all this you are at liberty to seck your other friends among the guests. If you are personally a stranger to the newly married couple, but have received a card from being a friend of one of the families or from any other reason, it is the first groomsman’s place to introduce you, and you should give him your card, or mention your name, before he leads you to the bride….
