This narrative is told about two friends, Simon and Molly, who play together every day, alone. When another young girl, Hester, moves in, Simon is jealous of the new relationship that Molly has built with Hester. As a teacher, I would use this book to show students that it is okay to have more than one best friend. I often see, in a classroom, children fighting about "he's my friend," or "she doesn't want to be my friend anymore." This book does a great job showing that it is okay to have multiple best friends. I appreciate Lisa Jahn-Clough, the author and illustrator, because she really captures the complexities of friendship, and also uses bright, child-like, pictures that students can relate to.
