If he gets on a street car and the car gives a lurch just as he is about to be seated and throws him against another passenger, he lifts his hat and says "Excuse me!" or "I beg your pardon!" He must _not_ say "Pardon _me_!" He must not take a seat if there are ladies standing. But if he is sitting and ladies enter, should they be young, he may with perfect propriety keep his seat. If a very old woman, or a young one carrying a baby, enters the car, a gentleman rises at once, lifts his hat slightly, and says: "Please take my seat." He lifts his hat again when she thanks him. If the car is very crowded when he wishes to leave it and a lady is directly in his way, he asks: "May I get through, please?" As she makes room for him to pass, he lifts his hat and says: "Thank you!" If he is in the company of a lady in a street car, he lifts his hat to another gentleman who offers her a seat, picks up something she has dropped, or shows her any civility. He lifts his hat if he asks anyone a question, and always, if, when walking on the street with either a lady or a gentleman, his companion bows to another person. In other words, a gentleman lifts his hat whenever he says "Excuse me," "Thank you," or speaks to a stranger, or is spoken to by a lady, or by an older gentleman. And no gentleman ever keeps a pipe, cigar or cigarette in his mouth when he lifts his hat, takes it off, or bows. =THE BOW OF CEREMONY= The standing bow, made by a gentleman when he rises at a dinner to say a few words, in response to applause, or across a drawing-room at a formal dinner when he bows to a lady or an elderly gentleman, is usually the outcome of the bow taught little boys at dancing school. The instinct of clicking heels together and making a quick bend over from the hips and neck, as though the human body had two hinges, a big one at the hip and a slight one at the neck, and was quite rigid in between, remains in a modified form through life. The man who as a child came habitually into his mother's drawing-room when there was "company," generally makes a charming bow when grown, which is wholly lacking in self-consciousness. There is no apparent "heel-clicking" but a camera would show that the motion is there. In every form of bow, as distinct from merely lifting his hat, a gentleman looks at the person he is bowing to. In a very formal standing bow, his heels come together, his knees are rigid and his expression is rather serious. =THE INFORMAL BOW= The informal bow is merely a modification of the above; it is easy and unstudied, but it should suggest the ease of controlled muscles, not the floppiness of a rag doll.
