Sell Things by the Tariff of Courtesy. You oblige people most that way. The bid of an interested buyer will never equal the return gift of an honourable recipient of a favour. Courtesy does not really make presents, but really lays men under obligation, and generosity is the great obligation. To a right-minded man nothing costs more dear that what is given him: you sell it him twice and for two prices: one for the value, one for the politeness. At the same time it is true that with vulgar souls generosity is gibberish,for they do not understand the language of good breeding.
