You’re in your room, reading the newest book by your favorite author, but you’re getting sleepy. You reach for the bookmark your best friend made for you, but you suddenly realize: you left it in your last library book, and you have already returned it!
You know you won’t be able to sleep until you find it, so you decide to go to the library to see if it is there. You hop on your bike and ride down the street to the library, but it is closed! Maybe someone is there who can help you.
