“People are ruder today because they are rushed and more ‘time poor’ than ever before,” says Patsy Rowe, “ Manners have fallen off the radar(雷达).” Due to our strong attraction to electronic equipment it is a wonder more people don’t wake up each morning and greet the singing birds with a complaint（抱怨）about the noise. Here are some examples of rudeness.

   Some people prefer to do almost everything over the internet. To them, dealing with an actual human is like an evolutionary step backward. It feels very slow because humans don’t work at 4G speeds. When you have dinner with friends, you will often notice someone paying more attention to his mobile phone. We have programmed ourselves to think that every new message brings life-changing news, so taking calls and checking our texts are more important than talking to the people we are with. What is worse, some people even tend to send anonymous（匿名的）rude messages by email.

However, rudeness is never acceptable. Don^’t assume it is OK to be rude if the person you’re in touch with won^’t recognize you. If you have something awful to say, have the courage to face the person and say it, write a letter or email and sign it, or forget it. Upsetting people with unsigned messages is cruel and disgusting.

We shouldn^’t blame technology for our shortcomings. Technology is here to help us, but we should not allow it to take over our lives. An important step is acknowledging our shortcomings. People spend a lot of time pointing out bad manners but it would be even more helpful if we’d publicly acknowledge good manners when we see them.
