Friendship is like money, easier made than kept.
A true friend is the greatest of all blessings, and that which we take the least care of all to acquire.
Friendship marks a life even more deeply than love. Love risks degenerating into obsession, friendship is never anything but sharing.
Friendship is the shadow of the evening, which strengthens with the setting sun of life.
True friends are like diamonds – bright, beautiful, valuable, and always in style.
