A great handshake””at home or abroad
In North America and Europe, a firm handshake is an appropriate form of greeting. In Asia and the Middle East, where hand shaking is still relatively new, the customary grip is gentler; a too-hearty grip could be interpreted as aggressive. In Islamic countries, offering your hand to a woman is highly offensive. At the other extreme, it’s said that you can never shake hands too much in France, whre women shake hands as freely and as often as men.
