There is a story of a father who saw that his young son had a tendency to certain vices. He told him often to keep away from them but the boy would not listen. He did everything in his power; in the end, when he was dying, he called his son and said, "Now I will never tell you any more not to do things that you have always liked to do. But will you remember the last words of your father, that whenever you want to gamble you must gamble with the greatest gamblers, and whenever you feel like drinking you must drink with great drunkards."
