Another common desire which you must sternly repress is the wish to meddle in another man's business, directly or indirectly, privately or openly. If you see a case of cruelty to a child or an animal, it is your duty to interfere. If you are placed in charge of another in order to teach him, it may become your duty gently to tell him of his faults. Except for such cases, mind your own business and learn the value of silence.
