Notes may be regarded as letters in miniature confined chiefly to invitations, acceptances, regrets and introductions, and modern etiquette tends towards informality in their composition. Card etiquette, in fact, has taken the place of ceremonious correspondence and informal notes are now the rule. Invitations to dinner and receptions are now mostly written on cards. "Regrets" are sent back on visiting cards with just the one word "Regrets" plainly written thereon. Often on cards and notes of invitation we find the letters R. S. V. P. at the bottom. These letters stand for the French repondez s'il vous plait, which means "Reply, if you please," but there is no necessity to put this on an invitation card as every wellbred person knows that a reply is expected. In writing notes to young ladies of the same family it should be noted that the eldest daughter of the house is entitled to the designation Miss without any Christian name, only the surname appended. Thus if there are three daughters in the Thompson family Martha, the eldest, Susan and Jemina, Martha is addressed as Miss Thompson and the other two as Miss Susan Thompson and Miss Jemina Thompson respectively.
