“You're rather adorable when you're mad and can't do anything about it, you know.”

“Of course it's very hampering being a detective, when you don't know anything about detecting, and when nobody knows that you're doing detection, and you can't have people up to cross-examine them, and you have neither the energy nor the means to make proper inquiries; and, in short, when you're doing the whole thing in a thoroughly amateur, haphazard way.”

“Cheshire Puss,' [Alice] began, rather timidly, "`But I don't want to go among mad people,' Alice remarked. Oh, you can't help that,' said the Cat: `we're all mad here. I'm mad. You're mad.' How do you know I'm mad?' said Alice. You must be,' said the Cat, `or you wouldn't have come here.' Alice didn't think that proved it at all; however, she went on `And how do you know that you're mad?' To begin with,' said the Cat, `a dog's not mad. You grant that?' I suppose so,' said Alice. Well, then,' the Cat went on, `you see, a dog growls when it's angry, and wags its tail when it's pleased. Now I growl when I'm pleased, and wag my tail when I'm angry. Therefore I'm mad.”

“It's so much easier to convince yourself you're madly in love with someone when you know nothing about him.”

“If you're going to remember anything from your past, then do so fondly because you can't change a thing about it.”

“You're not dying, you just can't think of anything good to do.”
