Both reality and manner
Substance is not “stance” enough : you must also heed circumstance. The wrong manner turns everything sour, even justice and reason. The right one makes up for everything : it turns a “no” golden, sweetens truth, and makes even old age look pretty. The “how” of things is very important, and a pleasant manner captures the affection of others. A bel portarse is precious in life. Speak and act well and you will get out of any difficult situation.
