Friendship is like a debt of honour; the moment it is talked of, it loses its real name and assumes the more ungrateful form of obligation.
Goldsmith
Have friends, not for the sake of receiving, but of giving.
Joseph Roux
Amongst true friends there is no fear of losing anything.
Jeremy Taylor
When men are friends, there is no need of justice; but when they are just, they still need friendship.
Aristotle
