Alice's Adventures in Wonderland and Through the Looking-Glass
"I went to the Classical master, though. He was an old crab, he was."
"I never went to him," the Mock Turtle said with a sigh. "He taught Laughing and Grief, they used to say." (Wonderland 9.82-83)
"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." (Wonderland 9.85-88)
"We gave you the opportunity of doing it," the Red Queen remarked: "but I daresay you've not had many lessons in manners yet?"
"Manners are not taught in lessons," said Alice. "Lessons teach you to do sums, and things of that sort."
