“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.”

“Have i gone mad?
I'm afraid so, but let me tell you something, the best people usually are.” 

― Lewis Carroll, Alice in Wonderland
