Philip Stanhope, 4th Earl of Chesterfield Quote

Talk often, but never long; in that case, if you do not please, at least you are sure not to tire your hearers. Pay your own reckoning, but do not treat the whole company; this being one of the few cases in which people do not care to be treated, every one being fully convinced that he has wherewithal to pay.
