The friend who holds up before me the mirror, conceals not my smallest faults, warns me kindly, reproves me affectionately, when I have not performed my duty, he is my friend, however little he may appear so. But if a man praises and lauds me, never reproves me, overlooks my faults, and forgives them before I have repented, he is my enemy, however much he may appear my friend.
I use the verb 'to torment,' as I observed to be your own method, instead of 'to instruct,' supposing them to be now admitted as synonymous.
