Twain's 'Advice to Little Girls'
If at any time you find it necessary to correct your brother, do not correct him with mud—never, on any account, throw mud at him, because it will spoil his clothes. It is better to scald him a little, for then you obtain desired results. If your mother tells you to do a thing, it is wrong to reply that you won't. It is better and more becoming to intimate that you will do as she bids you, and then afterward act quietly in the matter according to the dictates of your best judgment.
