The desire to give advice is itself a symptom of disapproval; and further, it is usually the result of a desire to express that disapproval. And we are most moved to give advice to those for whom our affection and regard may be taken for granted, but to whom we would rather express our disapproval. We cannot go to them and say that we disapprove of them. That would not be affectionate, and might lead to reprisals. But we can give them advice in which the disapproval is implied and which yet seems innocently helpful.
John William MackailBefore you give advice, that is to say advice which you have not been asked to give, it is well to put to yourself two questions - namely, what is your motive for giving it, and what is it likely to be worth? If these questions were always asked, and honestly answered, there would be less advice given.
