“I'm not often bored,' I assured her. "Life's not long enough for that.”

Context: To begin an affair of that kind now, and carry it on so long a time in form, is by no means a proper plan … whatever assurances I may give her in private of my esteem for her, or whatever assurances I may ask in return from her, depend on it — they must be kept in private. Necessity will oblige me to proceed in a method which is not generally thought fair; that of treating with a ward before obtaining the approbation of her guardian. I say necessity will oblige me to it, because I never can bear to remain in suspense so long a time. If I am to succeed, the sooner I know it, the less uneasiness I shall have to go through. If I am to meet with a disappointment, the sooner I know it, the more of life I shall have to wear it off: and if I do meet with one, I hope in God, and verily believe; it will be the last.
