“The rule is, jam tomorrow and jam yesterday—but never jam today.”
“It must come sometimes to ‘jam today,’” Alice objected.
“No, it can’t,” said the queen. “It’s jam every other day: today isn’t any other day, you know.”
“I don’t understand you,” said Alice. “It’s dreadfully confusing!’’
“That’s the effect of living backward,” the queen said kindly. “It always makes one a little giddy at first—”
“Living backward!” 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 backward,” the queen remarked.
“What sort of things do you remember best?” Alice ventured to ask.
“Oh, things that happened the week after next,” the queen replied in a careless tone. “For instance, now,” she went on, sticking a large piece of plaster on her finger as she spoke, “there’s the king’s messenger. He’s in prison now, being punished—and the trial doesn’t even begin till next Wednesday; and of course the crime comes last of all.”
