Who does not believe his first passion eternal? - William Makepeace Thackeray

Young ladies may have been crossed in love, and have had their sufferings, their frantic moments of grief and tears, their wakeful nights, and so forth; but it is only in very sentimental novels that people occupy themselves perpetually with that passion; and, I believe, what are called broken hearts are very rare articles indeed.

When one man has been under very remarkable obligations to another, with whom he subsequently quarrels, a common sense of decency, as it were, makes of the former a much severer enemy than a mere stranger would be. To account for your own hard-heartedness and ingratitude in such a case, you are bound to prove the other party's crime. It is not that you are selfish, brutal, and angry at the failure of a speculation — no, no — it is that your partner has led you into it by the basest treachery and with the most sinister motives. From a mere sense of consistency, a persecutor is bound to show that the fallen man is a villain — otherwise he, the persecutor, is a wretch himself.

I can't help always falling upon it, and cry out with particular loudness and wailing, and become especially melancholy, when I see a dead love tied to a live love.
