" Politeness must be cultivated, for the promptings of nature are eminently selfish, and courtesy and good-breeding are only attainable by effort and discipline. But even courtesy has limits where dignity should govern it, for when carried to excess, particularly in manner, it borders on sycophancy, which is almost as despicable as rudeness. "
