How to spot a best friend

On the way to school, a child lists all the qualities that differentiate a best friend from a friend. When the narrator announces, "Today, I will find a best friend!" Mama is a little dubious. It's just the first day of school, after all. This kid is confident it will happen "like that!" and proceeds to describe what makes a best friend. A regular friend may lend a crayon, but "a best friend lends you a brand-new, extra-sharp green crayon. Even if you're drawing a tree with 3,811 green leaves." Similarly, regular friends sit next to you at storytime, help you build block towers, and swing with you; best friends hold your hand if the story is scary, rebuild fallen towers with you, and push you on the swings. As the child, who, like Mama, presents White, continues the litany, the illustrations alternate between views of the child and Mama and the scenarios the child describes being played out at school, with a different member of the class occupying the best-friend role in each. These classmates are racially diverse; two wear glasses, and one uses a wheelchair. By the end, readers may be a little worn down by the level of self-sacrifice expected of this hypothetical best friend, but the child's final statement that the "number one, guaranteed best way to spot a best friend" is "to be a best friend, too" promises reciprocity. Hopeful, if a little relentless. (Picture book. 4-7) Copyright (c) Kirkus Reviews, used with permission.
