Courtesy demands that you, when you are a guest, shall show neither annoyance nor disappointment--no matter what happens.
Emily PostTo be a good sportsman, one must be a stoic and never show rancor in defeat, or triumph in victory, or irritation, no matter what annoyance is encountered. One who can not help sulking, or explaining, or protesting when the loser, or exulting when the winner, has no right to take part in games or contests.
Emily PostTraining a child is exactly like training a puppy; a little heedless inattention and it is out of hand immediately; the great thing is not to let it acquire bad habits that must afterward be broken.
