“Others again would say that Friendship is extremely useful, perhaps necessary for survival, to the individual. They could produce plenty of authority: "bare is the back without a brother behind it" and "there is a friend that sticketh closer than a brother". But when we speak thus we are using friend to mean "ally". In ordinary usage friend means, or should mean, more than that. A Friend will, to be sure, prove himself to be also an ally when alliance becomes necessary; will lend or give when we are in need, nurse us in sickness, stand up for us among our enemies, do what he can for our widows and orphans. But such good offices are not the stuff of Friendship. The occasions for them are almost interruptions. They are in one way relevant to it, in another not. Relevant, because you would be a false friend if you would not do them when the need arose; irrelevant, because the role of benefactor always remains accidental, even a little alien, to that of Friend. It is almost embarrassing. For Friendship is utterly free of Affection's need to be needed. We are sorry that any gift or loan or night-watching should have been necessary--and now, for heaven's sake, let us all forget about it and go back to the things we really want to do or talk of together. Even gratitude is no enrichment to this love. The stereotyped "Don't mention it" here expresses what we really feel. The mark of perfect Friendship is not that help will be given when the pinch comes (of course it will) but that, having been given, it makes no difference at all.”
