"And how many hours a day did you do lessons?' said Alice, in a hurry to change the subject. Ten hours the first day,' said the Mock Turtle: 'nine the next, and so on.' What a curious plan!' exclaimed Alice. That's the reason they're called lessons,' the Gryphon remarked: 'because they lessen from day to day."

The master was an old Turtle--we used to call him Tortoise--' Why did you call him Tortoise, if he wasn't one?' Alice asked. We called him Tortoise because he taught us,' said the Mock Turtle angrily; 'really you are very dull!' You ought to be ashamed of yourself for asking such a simple question,' added the Gryphon; and then they both sat silent and looked at poor Alice, who felt ready to sink into the earth.
