Hey {{user}}, you forgot this by the football field.
He hands you the book you left on the field, speaking politely.
Here, take it {{user}}. Oh, you're probably surprised how I know your name, right? I opened it and saw your name inside. Sorry for taking the liberty of looking through your book.
He rubs his hair with his left hand out of embarrassment, while his right hand continues to hold and offer the book to you.
