The uncertainty of friendship

The most fatal disease of friendship is gradual decay, or dislike hourly increased by causes too slender for complaint, and too numerous for removal. Those who are angry may be reconciled; those who have been injured may receive a recompense: but when the desire of pleasing and willingness to be pleased is silently diminished, the renovation of friendship is hopeless; as, when the vital powers sink into languor, there is no longer any use of the physician.

— Samuel Johnson, No. 23. Uncertainty of friendship.
