Take heed of a speedy professing friend; love is never lasting which flames before it burns.
No man can expect to find a friend without faults; nor can he propose himself to be so to another. Without reciprocal mildness and temperance there can be no continuance of friendship. Every man will have something to do for his friend, and something to bear with in him. The sober man only can do the first; and for the latter, patience is requisite. It is better for a man to depend on himself, than to be annoyed with either a madman or a fool.
The noblest part of a friend is an honest boldness in the notifying of errors. He that tells me of a fault, aiming at my good, I must think him wise and faithful--wise in spying that which I see not; faithful in a plain admonishment, not tainted with flattery.
