Avoid any air of mystery when speaking to those next you; it is ill-bred and in excessively bad taste.
If you wish to speak of any one, or to any one at the table, call them by name, but never point or make a signal when at table.
When taking coffee, never pour it into your saucer, but let it cool in the cup, and drink from that.
If at a gentleman’s party, never ask any one to sing or tell a story; your host alone has the right thus to call upon his guests.
If invited yourself to sing, and you feel sufficiently sure that you will give pleasure, comply immediately with the request.
If, however, you refuse, remain firm in your refusal, as to yield after once refusing is a breach of etiquette.
When the finger-glasses are passed, dip your fingers into them and then wipe them upon your napkin.
Never leave the table till the mistress of the house gives the signal.
On leaving the table put your napkin on the table, but do not fold it.
Offer your arm to the lady whom you escorted to the table.
