"I don't understand you," said Alice. "It's dreadfully confusing!"
"That's the effect of living backwards," the Queen said kindly: "it always makes one a little giddy at first... "
"Living backwards!" Alice repeated in great astonishment. "I never heard of such a thing!"
"...but there's one great advantage in it, that one's memory works both ways."
"I'm sure mine only works one way" Alice remarked. "I can't remember things before they happen."
"It's a poor sort of memory that only works backwards," the Queen remarked.
