'Affirmation is genuine appreciation, expressed quietly to another person, for what they have done. It is standing alongside someone who has been criticized. If the criticism was deserved, affirmation lets them know that you still believe in them; and if not, that they should ignore it and confidently get on with life. Affirmation is that thoughtful word, expressed in person, on the phone or by letter, that demonstrates how helped you were by your brother or sister.'
Peter Brain, Going the Distance, p.148.
