Excepting a religious ceremonial, there is no occasion where greater dignity of manner is required of ladies and gentlemen both, than in occupying a box at the opera. For a gentleman especially no other etiquette is so exacting.
Emily PostChildren 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 PostNever so long as you live, write a letter to a man - no matter who he is - that you would be ashamed to see in a newspaper above your signature.
