    Some people are so rude. Who sends an e-mail or a text message that just says “Thank you?” Who leaves a voice mail message rather than texts you? Who asks for a fact easily found on the Internet? 1.

Maybe I’m the rude one for not appreciating life’s little courtesies(礼节). But many social norms(规范) just don’t make sense to people drowning in digital communication.

Take the thank-you note. Daniel Post Senning, a coauthor of Emily Post’s Etiquette，asked, “At what point does showing appreciation outweigh the cost?”

2. Think of how long it takes to listen to one of those messages. In texts, you don’t have to declare who you are or even say hello. E-mail, too, is slower than a text. The worst are those who leave a voice mail and then send an e-mail message to tell you they left a voice mail.

This isn’t the first time technology has changed our manners, 3. Alexander Graham Bell, the inventor, suggested that people say, " Ahoy! "Finally, hello won out, and the victory sped up the greeting's use in face-to-face communications.

In the age of the smart phone, there is no reason to ask once-acceptable questions about:the weather forecast, a business’s phone number, or directions to a house, a restaurant, or an office, which can be easily found on a digital map. 4. And when you answer, they respond with a thank-you e-mail.

How to handle these differing standards? Easy: Consider your audience. Some people,especially older ones, appreciate a thank-you message. 5. In traditional societies, the young learn from the old. But in modern societies, the old can also learn from the young. Here's hoping that politeness never goes out of fashion but that time-wasting forms of communication do.

A. Then there is voice mail.

B. Others, like me, want no reply.

C. But people still ask these things.

D. Don’t these people realize that they’re wasting your time?

E. Won't new technology bring about changes in our daily life?

F. Face-to-face communication makes comprehension much easier.

G. When the telephone was invented, people didn't know how to greet a caller.
