Charlie Brown, wearing a cap and holding a book, approaches Patty, who is sitting on the curb holding her doll. He says,"I'm returning this book to the library"
As she walks along with him, he continues,"I finished it in one day!"
She follows him up the stairs and says,"I didn't know you could even read, Charlie Brown..."
He stops and turns to her, holding out the book. He exclaims,"Do you think I could finish this book in one day if I knew how to read?!"
