““Do not expect too much of others. ... . This is to expect of another a degree of altruism which is contrary to reason, since the loss to the altruist is greater than the gain to the egoist. In all your dealings with other people, especially with those who are nearest and dearest, it is important and not always easy to remember that they see life from their own angle and as it touches their own ego, not from your angle and as it touches yours. No person should be expected to distort the main lines of his life for the sake of another individual. On occasion there may exist such a strong affection that even the greatest sacrifices become natural, but if they are not natural they should not be made, and no person should be held blameworthy for not making them.””
