     Americans, generally speaking, make an effort to be friendly with their colleagues, neighbours and other

people they often run into. This often takes the form of a simple greeting like "How's it going?" or "What's up?"

This is simply a way of saying I see you and I recognize you.

     Americans also show this friendliness in "small talk". Small talk is a casual conversation that Americans

engage in when they meet on the street, in the shop or in the office before a meeting. Usually the topics of

such small talk will be something that everyone is familiar with, the weather, sports, traffic, hobbies or what's

on television. The topic of the conversation is not as important as the effort make to spend a few minutes with

the other person. Small talk shows that you are a considerate person who is interested in others and who is

willing to take the time to get to know people.

     Small talk is used in the business world to create a friendly atmosphere and to put everyone at ease before

the serious matters of business are discussed. Often businessmen will spend a few minutes talking about the

weather or sports before a meeting. This form of small talk only lasts a few minutes before the American

businessman wants to "get down to business."

     Asians are very skilled at making casual conversation. However, they often find it difficult to make small

talk with Americans because they don't know what to say, how to say it and who to say it to. Americans may

see Asians who are reluctant to make small talk as unfriendly and cold.
