Manners are a sensitive awareness of the feelings of others.

An overdose of praise is like 10 lumps of sugar in coffee; only a very few people can swallow it.

Never say "Au revoir" unless you have been talking French, or are speaking to a French person.

A gentleman should never take his hat off with a flourish.

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.

Never think, because you cannot write a letter easily, that it is better not to write at all. The most awkward note imaginable is better than none.
