to each other.

1 was walking in the park with a friend recently, and his mobile phone rang, interrupting our conversation. There we were, walking and talking on a beautiful sunny day and - poof! -1 was cut off as if I had become absent from the conversation.

The park was filled with people talking on their cell phones. They were passing people without looking at them, saying hello, noticing their babies or stopping to pat their dogs. It seems that the limitless electronic voice is preferred to human contact.

The telephone is used to connect you to the absent. Now it makes people feel absent.

Recently l was in a car with three friends. The driver hushed the rest of us because he could not hear the person on the other end of his cell phone. There we were, four friends driving down the highway, unable to talk to each other because of the small thing designed to make communication easier.

Why is it that the more connected we get, the more disconnected I feel？ Every advance in communication technology is a setback(退步) to the closeness of human interaction.

With e-mail and instant message over the Internet, we can now communicate without seeing or talking to one another. With voice mail, you can make entire conversations without ever reaching anyone. If my mom has a question, Ijust leave the answer on her machine.

As almost every contact between human beings gets automatic, the emotional Distance index goes up. Pumping gas at the station？ Why say good-morning to the assistant when you can swipe you credit card at the pump and save yourself the bother of human contact？

Making a deposit at the bank？ Why talk to the clerk who lives in the neighborhood when you Ctin put your Ctird into the ATM l More and more, I find myself hiding behind e-mail to do a job meant for conversation orbeing relieved that voice mail picked up because I didn’t really have time to talk.

The technology devoted to helping me keep in touch is making me lonelier. I own a mobile phone, an ATM card, a voice-mail telephone, and an e-mail account.

Giving them up isn’t a choice. They are great for what they are intended to do. It’s their unintended results that make me upset. What good is all this gee-whiz technology if there isno one in the room to hear you crying out Gee whiz ？

ignificant factor in all body languages. This is particularly true of personal space needs. For example, Dr. Edward Hall has shown that in Japan crowding together is a sign of warm and pleasant intimacy. In certain situations, Hall believes that the Japanese prefer crowding.

Donald Keene, who wrote Living Japan, notes the fact that in the Japanese language there is no word for privacy. Still, this does not mean that there is no concept of the need to be apart from others. To the Japanese, privacy exists in terms of his house. He considers this area to be his own, and he dislikes invasion of it. The fact that he crowds together with others does not contradict his need for living space.

Dr. Hall sees this as a reflection of the Japanese concept of space. Westerners, he believed, see space as the distance between objects; to them space is empty. The Japanese, on the other hand, see space as having as much meaning as their flower arrangements and art, and the shape of their gardens as well, where units of space balance the areas containing flowers or plants.

Like the Japanese, the Arabs too prefer to be close to one another. But while in public they are crowded together, in privacy, they prefer a great deal of space. The traditional or wealthy Arab house is large and empty, with family often crowded together in one small area of it. The Arabs do not like to be alone, and even in their spacious. houses they will huddle together.

The difference between the Arab huddling and the Japanese crowding is a deep thing. Tile Arabs like to touch his companion. The Japanese, in their closeness, preserve a formality and a cool dignity. They manage to touch and still keep rigid boundaries. The Arabs push these boundaries aside.

Along with this closeness, there is a pushing and shoving in the Arab world that many Westerners find uncomfortable, even unpleasant. To an American, for example, there are personal boundaries even in a public place. When he is waiting in line, he believes that his place there is his alone, and may not be invaded by another. The Arab has no concept of privacy in the public place, and if he can rush his way into a line, he feels perfectly within his rights to do so. To an American, the body is sacred; he dislikes being touched by a stranger, and will apologize if he touches another accidentally. To an Arab, bodily contact is accepted.

Hall points out that an Arab needs at times to be alone, no matter how close he wishes to be, physically, to his fellow men. To be alone, he simply cuts off the lines of communication. He retreats into himself, mentally and spiritually, and this withdrawal is respected by his companions. If an American were with an Arab who withdrew in this way, he would regard it as impolite, as lack of respect, even as an insult.
