Boy meets girl in this story of reluctant friendship that introduces young readers to the concept of similes

Summer drags, like a book that starts out good, then isn't. The boy is bored, like a frog waiting for a fly to buzz by. So the boy hops on his bike and heads for the playground, where he finds a girl on a swing who beckons him to join her. At first, the boy is reluctant, but soon they are having fun like best friends, like characters in a book with a happy ending.
