Young dark man, fake, mean and treacherous.
While declaring his friendship, he meditates inwardly on betraying you; his morals are light, his associates deplorable.
Very talkative, he easily discloses to anyone what you have entrusted to him in good faith; even the most serious things he has sworn not to say. He does not hinder himself in any way to perjure himself, as long as it can attract him a profit, however small it may be.
