 This is Kusha Navidar. Mo Willems has been writing kids' books for over 20 years, and if you know anything about kids' books, you probably recognize a lot of classic titles that he's responsible for. I'm talking about Knuffle Bunny, one of my favorites, Don't Let the Pigeon Drive the Bus, and the Elephant and Piggy series. And it was that series where New Yorker writer Rivka Galchin started when she sat down with Willems and asked him for a reading.
