The many faces of intimacy: the Victorians could experience it through correspondence, but not through cohabitation; contemporary men and women can experience it through fornication, but not through friendship.
The real test of friendship is Can you literally do nothing with the other person Can you enjoy together those moments of life that are utterly simple They are the moments people look back on at the end of life and number as their most sacred experiences.
To cement a new friendship, especially between foreigners or persons of a different social world, a spark with which both were secretly charged must fly from person to person, and cut across the accidents of place and time.
To reprehend well is the most necessary and the hardest part of friendship. Who is it that does not sometimes merit a check, and yet how few will endure one? Yet wherein can a friend more unfold his love than in preventing dangers before their birth, or in bringing a man to safety who is travelling on the road to ruin? I grant there is a manner of reprehending which turns a benefit into an injury, and then it both strengthens error and wounds the giver. When thou chidest thy wandering friend do it secretly, in season, in love, not in the ear of a popular convention, for oftentimes the presence of a multitude makes a man take up an unjust defence, rather than fall into a just shame.
Tolerance or forbearance of one's differences or weaknesses is what gives rise to a lasting friendship or relationship. I mean, without tolerance or forbearance there can't/won't be any lasting friendship or relationship. Thus, be and remain tolerant or forbearing.
