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. – Cornelia Otis Skinner

The most deadly fruit is borne by the hatred which one grafts on an extinguished friendship. – Gotthold Ephraim Lessing

It is one of the severest tests of friendship to tell your friend his faults. So to love a man that you cannot bear to see a stain upon him, and to speak painful truth through loving words, that is friendship. – Henry Ward Beecher
