I was in my third year of teaching writing at Ralph High School in New York, when one of my students, 15-year-old Mikey, gave me a note from his mother. It explained his absence (缺席) from class the day before:

"Dear Mr. McCort, Mikey’s grandmother, who is eighty years of age, fell down the stairs from too much coffee and I kept Mikey at home to take care of her and his baby sister so I could go to my job. Please excuse Mikey and he’ll do his best in the future. P.S. His grandmother is OK. "

I had seen Mikey writing the note at his desk. I said nothing. Most parental-excuse notes I received were penned by my students. If I were to deal with them, I’d be busy 24 hours a day. The writers of those notes didn’t realize that honest excuse notes were usually dull : "Peter was late because the alarm clock didn’t go off. "

The students always said it was bard putting 200 words together on any subject, but when they produced excuse notes, they were excellent. So I decided to type out a dozen excuse notes and gave them to my classes. I said, "They’re supposed to be written by parents, but actually they are not. True, Mikey" The students looked at me nervously.

"Now, this will be the first class to study the art of the excuse note -the first class, ever, to practice writing them. " Everyone smiled as I went on, "Today I’d like you to write An Excuse Note from Adam to God’ or ’ An Excuse Note from Eve to God’. " Heads went down. Pens raced across paper. For the first time ever I saw students so immersed (专心的) in their writing, they had to be asked to go to lunch by their friends.

The next day everyone had excuse notes. Heated discussions followed. But suddenly I saw the headmaster at the door. He entered the classroom and walked up and down, looking at papers, and then said, "I’d like you to see me in my office. " My heart sank.

When I stepped into his office, he came to shake my hand and said, "I just want to tell you that that lesson, that task, whatever the hell you were doing, was great. Those kids were writing on the college level. Thank you. \

Mobile Phone Manners

Mobile phones have changed the way we communicate (交流); they have also brought about problems in phone manners (礼仪). Gaik Lira, a Singapore-based advisor, has some advice on phone manners.

When dealing with missed calls, the person being called should return the call. "Calls should be returned as soon as possible, and no later than the following day. Anything later than that, and an apology or a reason for the delay should go with the call. "

Text messages should be kept short and to the point. If they go beyond four or five lines, call or e-mail instead. "The use of short forms should be among family members and friends, never in a business situation. "

Speak in a low voice as if you were talking to someone next to you. If the connection is bad, don’t raise your voice in order to be heard, simply move to another place where the connection may be better. And if that doesn’t work, tell the caller to call you back or offer to call at a later time.

When a conversation is cut off due to a bad connection, the person who started the conversation should call back. "It may be inconvenient for the other person to return the call, especially if it’s an unlisted number, or an overseas call. "

When running late for a date or meeting, it is acceptable to text to inform that you’ll be delayed. Messages should be apologetic. "A message like ’ Sorry. Will be about 30 minutes late due to flight delay’ is considered polite and thoughtful. "

Taking calls during meetings is only acceptable if you have informed the chairperson that you are expecting an urgent (紧急的) call. If you get an unexpected but urgent call, apologize to those present and offer a quick explanation as to why you have to take that call. Then leave the room to continue your phone conversation.

Different countries have different cultures. A same gesture may have distinct meanings in different countries. For instance, in Africa, people knock at the table with their fingers to call waiters which is considered as impolite in China. In western countries, if you make a circle with your thumb and the index finger (食指), and then raise the other three fingers, you are suggesting "OK". The same gesture, however, means "money" in Japan while makes Brazilian people feel insulted (受侮辱的). With that in mind, you’d better learn about their custom before travelling to foreign countries.

Greeting is an important part of communication between people. When greeting someone, Americans tend to hold out their hands and look directly into his/her eyes and then smile. However, sometimes such behavior might bring nothing but misunderstanding in other countries. A handshake might not be accepted and looking others right in the eye can have different meanings.

Asian people regard physical contact as embarrassing; therefore, they do not shake hands. They have their own ways of greeting people. For Japanese, a slight bow of the head is enough. In Korea, women do not shake hands or hug with people; while men might shake hands accompanied by nodding the head once. In western Asia, Muslims do not make body contacts with women yet hug is generally accepted among men. Same thing happens on eye contact. In many countries, people avoid direct eye contact to show respect. This can cause misunderstanding, too. In fact, some Asian students have been regarded as lacking respect for their American teachers exactly because they failed to make eye contacts with their teachers.

Though different cultures seem to have different ways of greeting, smiling is taken as the universal gesture of friendliness. Smiling indicates happiness or agreement (同意) and it can also be used to mean "Excuse me" or "Please". So when you are not sure what to do, just smile.
