     Meeting people from another culture can be difficult. From the beginning, people may send the wrong

signal(信号). Or they may pay no attention to signals from another person who is trying to develop a

relationship.

     Different cultures emphasize (强调) the importance of relationship building to a greater or lesser

degree. For example, business in some countries is not possible until there is a relationship of trust. Even

with people at work, it is necessary to spend a lot of time in "small talk", usually over a glass of tea, before they do any job. In many European countries -- like the UK or France - people find it easier to build up a

lasting working relationship at restaurants or cafes rather than at the office.

     Talk and silence may also be different in some cultures. I once made a speech in Thailand. I had

expected my speech to be a success and start a lively discussion; instead there was an uncomfortable

silence. The people present just stared at me and smiled. After getting to know their ways better, I

realized that they thought I was talking too much. In my own culture, we express meaning mainly through

words, but people there sometimes feel too many words are unnecessary.

     Even within Northern Europe, cultural differences can cause serious problems. Certainly, English and

German cultures share similar values; however, Germans prefer to get down to business more quickly.

We think that they are rude. In fact, this is just because one culture starts discussions and makes decisions more quickly.

     People from different parts of the world have different values, and sometimes these values are quite

against each other. However, if we can understand them better, a multicultural environment will offer a

wonderful chance for us to learn from each other.
