Even today, a man with good manner will politely open the door for a lady, help her put on her coat when necessary and see her safely to the door of her home before a date. When a man takes a woman out for a dinner, it is considered impolite to help her with her chair when she gets up or sits down. On a crowding train or bus, it is proper for a man offer a woman his seat, particular if she is old or carries a baby. Even when it comes to shake hands, ladies come first. It is impolite for a man to extend his hand for a handshake upon first greeting. Unless a woman does not extend her hand to the man first, the man shouldn’t offer theirs.
