Tell a 200-word joke (at least 150 words)

There came a little girl outside the door, as if it was the first time to borrow a book. I saw her shyly swipe her card, and when I heard the beep, I was relieved and entered the loan area with a big smile on my face. She came to the bookshelf and looked for it carefully with a stiff smile, but after a long time, she still couldn't find the book to borrow. She was in a hurry.
