Body Language

Body language is of great importance to humans. 26________ However, many forms of body language we consider to be fine in our country can get us into trouble in other parts of the world. 27________ While Americans smile freely at strangers, in Russia this is considered strange and even impolite. In Asian countries a smile isn’t necessarily an expression of joy but it can be used to express pain.

 28________ In Latin America and the Middle East the acceptable distance is much shorter than what most Europeans and Americans feel comfortable with. Hand and arm movements as a form of body language are also very different among countries. Handshakes are usually acceptable almost everywhere, even between strangers; however, kissing on the cheek and touching on the shoulder or other body parts aren’t. 29________ This is why you should not touch others easily. 30________ In America and Latin America looking the other person in the eye is a sign of respect. But in Asian countries, prolonged eye contact is especially rude, so you should try your best not to do that.
