The Ladies' Book of Etiquette, and Manual of Politeness

You are not expected to recognize any friend on the opposite side of the street. Even if you see them, do not bow. Avoid "cutting" any one. It is a small way of showing spite, and lowers you more than your enemy. If you wish to avoid any further intercourse bow, coldly and gravely, but do not look at any one, to whom you are in the habit of bowing, and pass without bowing. If you do this, they may flatter themselves that they were really unrecognized, but a distant, cold bow will show them that you speak from civility only, not from friendship. In the street a lady takes the arm of a relative, her affianced lover, or husband, but of no other gentleman, unless the streets are slippery, or in the evening. When a lady walks with two gentlemen, she should endeavor to divide her attention and remarks equally between them. If you do stop in the street, draw near the walls, that you may not keep others from passing. Loud talking and laughing in the street are excessively vulgar. Not only this, but they expose a lady to the most severe misconstruction. Let your conduct be modest and quiet. If a gentleman, although a stranger, offers his hand to assist you in leaving a carriage, omnibus, or to aid you in crossing where it is wet or muddy, accept his civility, thank him, bow and pass on. If you wish to take an omnibus or car, see that it is not already full. If it is, do not get in. You will annoy others, and be uncomfortable yourself.
