Courtesy is doing that which nothing under the sun makes you do but human kindness. Courtesy springs from the heart; if the mind prompts the action, there is a reason; if there be a reason, it is not courtesy, for courtesy has no reason. Courtesy is good will, and good will is prompted by the heart full of love to be kind. Only the generous man is truly courteous. He gives freely without a thought of receiving anything in return.
