Susie and Roberto are putting on a puppet show and all of their friends have come to see it, including Louie. As the show begins, Louie becomes fascinated by the smiling puppet Gussie and shouts "Hello!" in front of a silent audience. After the show, Louie goes home and dreams about Gussie. When he wakes up, he discovers that his friends have left a gift for him. This classic Ezra Jack Keats story of love and generosity is as meaningful today as when it was first published more than twenty years ago.
