Alice's Adventures in Wonderland and Through the Looking-Glass
"There's no sort of use in knocking," said the Footman, "and that for two reasons. First, because I'm on the same side of the door as you are: secondly, because they're making such a noise inside, no one could possibly hear you." And certainly there was a most extraordinary noise going on within – a constant howling and sneezing, and every now and then a great crash, as if a dish or kettle had been broken to pieces.
"Please, then," said Alice, "how am I to get in?"
"There might be some sense in your knocking," the Footman went on, without attending to her, "if we had the door between us. For instance, if you were inside, you might knock, and I could let you out, you know." (Wonderland 6.6-8)
. . . she looked back once or twice, half hoping that they would call after her: the last time she saw them, they were trying to put the Dormouse into the teapot. (Wonderland 7.99)
Once more she found herself in the long hall, and close to the little glass table. "Now, I'll manage better this time," she said to herself, and began by taking the little golden key, and unlocking the door that led into the garden. Then she set to work nibbling at the mushroom (she had kept a piece of it in her pocket) till she was about a foot high: then she walked down the little passage: and then – she found herself at last in the beautiful garden, among the bright flower-beds and the cool fountains. (Wonderland 7.102)
