A man should not smoke in the presence of women unless bidden by them to do so.  Few women care to say that it is disagreeable when asked, hence the better course is to await permission.

  Women.  If a woman has true regard for herself,
       she should not indulge in smoking; if she
       does, it should be in absolute privacy.

SON.

  Balls.  A son should do all in his power to
       make the ball a success by finding partners
       for the women having none, seeing that the
       men are introduced to the women, and taking
       in to supper a woman without an escort.

  Cards.  When a mother is calling, she can leave
       cards of her son for the host and hostess if it
       is impossible for him to do so himself.

       A son entering society can have his cards
       left by his mother for a host and hostess. 
       Invitations to entertainments will follow.
