Mobile phones have renewed the interpersonal relationships. There is usually a notice on the door of a meeting room, which reads, “Please keep your mobile phones power off during the meeting.” However the meeting room invariably echoes with the mobile rings. Although we are all ordinary people with few matters of great urgency, we are reluctant to turn off our mobile phones unless absolutely necessary. Keeping the mobile phones on is a symbol of our connection with the world. Mobile phones reflect our thirst for social communication, as can always be seen in a phone user who comes to a sudden halt on his way, staring at the screen of his mobile phone for texting regardless of whether he is in the middle of a road or by a public toilet.
