Then you should say what you mean,' the March Hare went on.
`I do,' Alice hastily replied; `at least--at least I mean what I say--that's the same thing, you know.'
`Not the same thing a bit!' said the Hatter. `You might just as well say that "I see what I eat" is the same thing as "I eat what I see"!'
`You might just as well say,' added the March Hare, `that "I like what I get" is the same thing as "I get what I like"!'
`You might just as well say,' added the Dormouse, who seemed to be talking in his sleep, `that "I breathe when I sleep" is the same thing as "I sleep when I breathe"!'
