Walter Cox Green, The Book of Good Manners; a Guide to Polite Usage for All Social Functions
“ Women bow first to men when meeting in the street. A man may bow first if the acquaintance is intimate. When walking with a man, and they meet another unknown to her, but known to her escort, both men bow. If she meets a friend, man or woman, unknown to her escort, he bows. Unless an introduction has taken place at any function, no recognition is customary. It is the woman's privilege, however, to decide for herself whether she will recognize the guest or not. A man bowing and joining a woman on the street must ask permission to do so. She is at perfect liberty to gracefully decline. ”
