He who accepts benefits, and denies a return of them when needed, inflicts a real hurt, by disappointing one of the most natural and reasonable of expectations, and one which he must at least tacitly have encouraged, otherwise the benefits would seldom have been conferred. The important rank, among human evils and wrongs, of the disappointment of expectation, is shown in the fact that it constitutes the principal criminality of two such highly immoral acts as a breach of friendship and a breach of promise. Few hurts which human beings can sustain are greater, and none wound more, than when that on which they habitually and with full assurance relied, fails them in the hour of need; and few wrongs are greater than this mere withholding of good; none excite more resentment, either in the person suffering, or in a sympathising spectator.
