The Decameron (Day 3)

3.3- "I shall tell you this story dear ladies, not only in obedience to the order imposed upon me but to also make you aware that even the clergy in whom we place too much trust out of our excessive credulity, are capable of being cleverly deceived, as actually they sometimes are, not only by men but also by some of us women" suggests that trickery is often used as getting what you want easily, while lying is viewed as being rather well-supported way of getting ahead in life, going as far as to trick those who are seen as authoritative or rather held in high esteems (Boccaccio, 207). This, in itself, suggest that lying is a good thing.

4.9- "Though each man lived in his own castle, seperated by a distance of a good ten miles, Sir Guiglielmo de Guardastagno happened, nonetheless, to fall totally in love with the very beautiful and charming wife of Sir Guiglielmo Rossiglione, and notwithstanding the friendship and brotherhood that existed between them, he managed in one way or another to bring his love to the lady's attention..," displays that a rather interpersonal relationship was shared by the two before a woman came into the picture (Boccaccio, 350). This shows that is always a struggle for male-male dominance, even between friends. Revenge is seen in the harshest of ways, as a forbidden love can 'cause bonds such as the aforementioned brotherhood between the two Sirs to become to submissive.
