We ought to esteem him alone an agreeable and good-natured man, who, in his daily intercourse with others, behaves in such a manner as friends usuall… - Giovanni della Casa

When you go into public, let your dress be genteel, and suitable to your age and station of life. He that does otherwise, shows a contempt of the world, and too great an opinion of his own importance.

These kinds of habits, in good company, are so very nauseous and disgusting, that if we indulge ourselves in them, no one can be very fond of our acquaintance. So far from it, that even those, who are inclined to wish us well, must, by these and the like disagreeable customs, be entirely alienated from us.— Those ill-bred people, who expect their acquaintance to love and caress them, with all their foibles, are as absurd as a poor ragged cinder-wench; who should roll about upon an heap of ashes, scrabbling and throwing dust in the face of every one that passed by; and yet flatter herself that she should allure some youth to her embraces, by these dirty endearments; which would infallibly keep him at a distance.

You ought to regulate your manner of behaviour towards others, not according to your own humour, but agreeably to the pleasure and inclination of those with whom you converse.
