Famous quotes containing the word march:
““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. “Why you might just as well say that ‘I see what I eat’ is the same thing as ‘I eat what I see’!””
—Lewis Carroll [Charles Lutwidge Dodgson] (1832–1898)
