"That depends a good deal on where you want to get to," said the Cat.
"I don't much care where - " said Alice.
"Then it doesn't matter which way you go," said the Cat.
" - so long as I get somewhere," Alice added as an explanation.
"Oh, you're sure to do that," said the Cat, "if you only walk long enough."
... and this time it [the Cat] vanished quite slowly, beginning with the end of the tail, and ending with the grin, which remained some time after the rest of it had gone.
Lewis Carroll, Alice's Adventures in Wonderland
