In the first place, it is always customary in a city for a young
lady, either accompanied or unaccompanied, to walk on the
sidewalk. A young "miss" who persists in walking in the gutters
is more apt to lose than to make friends among the socially
"worth while."

Gentlemen, either with or without ladies, are never seen walking
after dark in the sewers or along the elevated, tracks.

It is not au fait for gentlemen or ladies wearing evening dress
to "catch on behind" passing ice wagons, trucks, etc.; the time
and energy saved are doubtfully repaid should one happen to be
driven thus past other members of one's particular social "set."

Ladies walking alone on the street after dark do not speak to
gentlemen unless they have been previously introduced or are out
of work with winter coming on.

A gentleman walking alone at night, when accosted by a young
woman whom he has not met socially, removes his hat politely,
bows and passes on, unless she looks awfully good.

Debutantes meeting traffic policemen always bow first in America;
in the Continental countries, with their age-old flavor of
aristocratic court life, this custom is reversed.

A bachelor, accompanied by a young unmarried woman, when stepping
accidentally into an open coal or sewer hole in the sidewalk,
removes his hat and gloves as inconspicuously as possible.
