And if through necessity you have to converse with such a person, be as brief as you can, and preserve a grave and modest demeanour, and let your words incline to harshness, rather than to excess of tenderness and affability.
Presume not on your own strength, if you are free, and have been for very many years free, from the temptations of the flesh; for this cursed vice does in an hour what for years it has failed to do, often making its advances stealthily; and the more it comes in the garb of a friend without exciting suspicion, the more grievous are the injuries and the more fatal the wounds it inflicts.
