One day a boy gave his girlfriend a Chinese display pager and said to her gently: I will never be afraid of not being able to find you again. The girl said naughtily: "If I leave this city, you won't be able to call me." The boy shook his head proudly: "I have a roaming policy, and I will call you no matter where you go." The girl asked him what his paging number was, and the boy said: "This is a love line, and the number is not public." From then on, the girl carried it with her every day and never left it for a moment...
