在一个风和日丽的下午，小镇上的图书馆里发生了一件趣事。汤姆，一个爱开玩笑的年轻人，走进了图书馆，想找一本有趣的书来消磨时间。他看到管理员正在整理书架，于是走过去打趣道：“嗨，玛丽！你的工作是不是太轻松了？这些书永远不会跑掉。”

玛丽微微一笑，回答说：“哦，汤姆，你错了。这些书虽然不会自己跑掉，但它们会‘飞’出去——借给读者们啊！”

汤姆被玛丽的话逗笑了，但他不甘示弱地继续说道：“那倒也是。不过，我觉得你的工作还是挺危险的。要是哪天有一本书对你发脾气，它可能会咬你一口呢！”

玛丽假装害怕地捂住胸口：“天啊！那我可得小心点，说不定哪本历史书会因为记恨我而报复我呢！”

两人相视大笑，整个图书馆充满了欢乐的气氛。其实，图书馆不仅是知识的殿堂，也是笑声的源泉。

English Version:

On a sunny afternoon, something funny happened in the library of a small town. Tom, a young man who loved to play jokes, walked into the library looking for an interesting book to pass the time. He saw Mary, the librarian, sorting books on the shelves and went over to tease her: "Hey, Mary! Isn't your job too easy? These books will never run away!"

Mary smiled slightly and replied: "Oh, Tom, you're wrong. Although these books won't run away by themselves, they can 'fly' out - lent to readers!"

Tom laughed at Mary's words, but he wasn't going to give up easily. He continued: "That's true. However, I think your job is still quite dangerous. If one day a book gets angry with you, it might bite you!"

Mary pretended to be scared and covered her chest: "Oh my god! Then I have to be careful. Who knows which history book will seek revenge on me!"

The two burst into laughter, and the whole library was filled with joyous atmosphere. In fact, the library is not only a hall of knowledge, but also a source of laughter.
