Gestures are woven into the texture of our everyday lives. When arguing or speaking animatedly, you can wave, point, beckon, or use your hands, sometimes expressing yourself with gestures without thinking. The sense of certain gestures may, however, be very distinct across cultures.
For example, the “OK” sign made by hand typically conveys a positive message in English-speaking countries, in countries such as Germany, Russia, and Brazil, it is considered offensive. So, to prevent misinterpretation, it’s important to be cautious about how you use gestures.
