Without some dissimulation no business can be carried on at all. - Philip Stanhope, 4th Earl of Chesterfield

Religion is by no means a proper subject of conversation in a mixed company.

Cheerful with wisdom, with innocence gay, And calm with your joys gently glide thro' the day. The dews of the evening most carefully shun — Those tears of the sky for the loss of the sun.

Let this be one invariable rule of your conduct—never to show the least symptom of resentment, which you cannot, to a certain degree, gratify; but always to smile, where you cannot strike.
