You are not to imagine that my friendship is light enough to be blown away by the first cross blast, or that my regard or kindness hangs by so slender a hair, as to be broken off by the unfelt weight of a petty offence. I love you, and hope to love you long. You have hitherto done nothing to diminish my goodwill, and though you had done much more than you have supposed imputed to you my goodwill would not have been diminished.

I write thus largely on this suspicion which you have suffered to enter your mind, because in youth we are apt to be too rigorous in our expectations, and to suppose that the duties of life are to be performed with unfailing exactness and regularity, but in our progress through life we are forced to abate much of our demands, and to take friends such as we can find them, not as we would make them.
