Fine as friendship is, there is nothing irrevocable about it. The bonds of friendship are not iron bonds, proof against the strongest of strains and the heaviest of assaults. A man by becoming your friend has not committed himself to all the demands which you may be pleased to make upon him. Foolish people like to test the bonds of their friendships, pulling upon them to see how much strain they will stand. When they snap, it is as if friendship itself had been proved unworthy. But the truth is that good friendships are fragile things and require as much care in handling as any other fragile and precious things. For friendship is an adventure and a romance, and in adventures it is the unexpected that happens. It is the zest of peril that makes the excitement of friendship. All that is unpleasant and unfavorable is foreign to its atmosphere; there is no place in friendship for harsh criticism or fault-finding. We will “take less” from a friend than we will from one who is indifferent to us. Good friendship is lived on a warm, impetuous plane; the long-suffering kind of friendship is a feeble and, at best, a half-hearted affair. It is friendship in the valley and not on the breezy heights. For the secret of friendship is a mutual admiration, and it is the realization or suspicion that that admiration is lessening on one side or the other that swiftly breaks the charm. Now this admiration must have in it no taint of adulation, which will wreck a friendship as soon as suspicion will. But it must consist of the conviction, subtly expressed in every tone of the voice, that each has found in the other friend a rare spirit, compounded of light and intelligence and charm. And there must be no open expression of this feeling, but only the silent flattery, soft and almost imperceptible. And in the best of friendships this feeling is equal on both sides. Too great a superiority in our friend disturbs the balance, and casts a sort of artificial light on the talk and intercourse. We want to believe that we are fairly equal to our friends in power and capacity, and that if they excel us in one trait, we have some counterbalancing quality in another direction. It is the reverse side of this shield that gives point to the diabolical insight of the Frenchman who remarked that we were never heartbroken by the misfortunes of our best friends. If we have had misfortunes, it is not wholly unjust and unfortunate that our friends should suffer too. Only their misfortunes must not be worse than ours. For the equilibrium is then destroyed, and our serious alarm and sympathy aroused. Similarly we rejoice in the good fortune of our friends, always provided that it be not too dazzling or too undeserved.
