umbrellas

A gentlemen never swaggers along the street, shouting or laughing with his companions, his hat on one side, a cigar between his fingers, or switching a cane to the danger or discomfort of passers-by.
If he's smoking and a lady passes by, he removes the cigar from his mouth.
When escorting a woman in the daytime, he does not offer her his arm unless she is old or ill unless for the purpose of protecting her in a large crowd.
He should not monopolize the umbrella when with two ladies in the rain. He should take the outside, holding it both over them.
