A friend reported gleefully that his small daughter had asked him, "What's the difference between litter and literature anyway, Dad?" He knew I'd relish both her question and his answer: "Sometimes, alas, not all that much."
I'll bet Amy Krouse Rosenthal would enjoy the partial homonym, if not the distinction. The author of more than 30 children's picture books, she loves wordplay. Her latest book for grownups, Textbook Amy Krouse Rosenthal, makes clear that she is on a mission to extend the playfulness of kid lit to adults.
