The mobile phone rule is just common polite behavior. Most people today have a mobile phone. In fact, many people can’t imagine how they ever get along without them. However, many people also complain(抱怨) about mobile phone users. People complain about other people loudly discussing personal matters in public places. They complain when mobile phones ring in movie theaters and concert halls. They complain about people driving too slow, and paying no attention to where they are going because they are talking  on a mobile phone. And they complain about people walking around talking to people who aren’t there.

Whenever a new communication technology becomes popular, it changes the way in which society is organized. Society has to invent rules for the polite way to use the new devices（装置）. Our rules of politeness for mobile phones are still evolving（发展；使逐渐形成）.

The mobile phone rule applies to most public places. Always try to have your phone ring as low as possible or put your mobile phone on the vibration（振动） mode, so it does not distract the people around you. The basic mobile phone rule includes:

1. Switch it off: Turn it off when you have meetings, worship, and so on.

2. Be brief: When you get a call and you’re with friends, keep the call short.
