" Pray, what are you laughing at?” inquired the Rocket; “I am not laughing.” “I am laughing because I am happy,” replied the Cracker. “That is a very selfish reason,” said the Rocket angrily. “What right have you to be happy? You should be thinking about others. In fact, you should be thinking about me. I am always thinking about myself, and I expect everybody else to do the same. That is what is called sympathy. It is a beautiful virtue, and I possess it in a high degree. "
