Alice couldn't help laughing, as she said, "I don't want you to hire me - and I don't care for jam."
"It's very good jam," said the Queen.
"Well, I don't want any today, at any rate."
"You couldn't have it if you did want it," the Queen said.
"The rule is, jam tomorrow and jam yesterday - but never 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.”
