In this illustrated picture book, Olive experiences contradictory emotions. The first day of school is exciting but also scary. When she attends a friend's birthday party, she is delighted for him but also jealous that the presents aren't for her. And when she thinks about her little sister, she's both glad and mad--for lots of reasons. Olive helps young readers explore the sometimes-contradictory ways they feel about significant events in their lives. Building social-emotional intelligence in children helps them to allow all of their emotions to coexist inside them. It's part of being human to feel many different ways--all at once.
