| Traveling to all corners of the world gets easier and easier. We live in a global village, but this does not mean that we all behave in the same way. Different people of different countries have their own way of life. Greetings: How should you behave when you meet someone for the first time? An American or Canadian shakes your hand firmly while looking you straight in the eyes. In many parts of Asia, there is no physical contact at all. In Japan, you should bow, and the more respect you want to show, the deeper you should bow. In Thailand, the greeting is made by pressing both hands together at the chest, as if you are praying, and bowing your head slightly. In both countries, eye contact is avoided as a sign of respect. |
