For often in battle there is no doubt that if a man will throw away his arms, and fall on his knees before his pursuers, he may escape death; and in other dangers there are other ways of escaping death, if a man is willing to say and do anything. The difficulty, my friends, is not in avoiding death, but in avoiding unrighteousness; for that runs faster than death.

Young people nowadays love luxury; they have bad manners and contempt for authority. They show disrespect for old people... contradict their parents, talk constantly in front of company, gobble their food and tyrannize their teachers.
