Children are all more or less little monkeys in that they imitate everything they see. If their mother treats them exactly as she does her visitors they in turn play "visitor" to perfection. Nothing hurts the feelings of children more than not being allowed to behave like grown persons when they think they are able.
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 PostTo make a pleasant and friendly impression is not alone good manners, but equally good business.
Emily PostThe good guest is almost invisible, enjoying him or herself, communing with fellow guests, and, most of all, enjoying the generous hospitality of the hosts.
