A friend is a person before whom I may be sincere. Before him I may think aloud.
—Emerson.
A faithful friend is the true image of the Deity.
—Napoleon.
A friend cannot be known in prosperity, and an enemy cannot be hidden in adversity.
True friends visit us in prosperity only when invited, but in adversity they come without invitation.
A friend may be often found and lost, but an old friend can never be found, and nature has provided that he cannot be easily lost.
