Another form of body language that is used differently, depending on the culture, is distance. In North America people don't generally stand as close to each other as in South America. Two North Americans who don't know each other well will keep a distance of four feet between them, whereas South Americans in the same situation will stand two to three feet apart. North Americans will stand closer than two feet apart only if they are having a confidential conversation or if there is intimacy between them.

Gestures are often used to communicate. We point a finger, raise an eyebrow, wave an arm – or move any other part of the body – to show what we want to say. However, this does not mean that people all over the world use the same gestures to express the same meanings. Very often we find that the same gestures can communicate different meanings, depending on the country. An example of a gesture that could be misinterpreted is sticking out the tongue. In many cultures it is a sign of making a mistake, but in some places it communicates ridicule. intimacy misinterpreted it.
