“Civility costs nothing and buys everything”
“It costs nothing to dream and everything not to”
“Everyone loves something for nothing...even if it costs everything.”
“It cost me everything, absolutely everything, but maybe it's not love if it doesn't cost us everything.”
“If you want to make a good first impression, smile at people. What does it cost to smile? Nothing. What does it cost not to smile? Everything, if not smiling prevents you from enchanting people.”
“I like to pay taxes. With them, I buy civilization.”
