Body language shows all kinds of feelings and is sometimes more important than spoken language.A smile is a usual facial expression----it shows that you are friendly to others. However, it does not always mean that you are happy. A smile can hide other feelings, like anger, fear, or worry.

In most countries, nodding the head up and down shows agreement, while shaking the head means that you do not agree, or that you would not like to do something. If you stand holding your arms across your chest, you may be protecting yourself---just from a conversation you do not want! If you sit looking at the person you are talking to and then turn toward to him, it shows that you are interested. If you roll your eyes and turn your head away, most likely you do not believe what you are hearing, or you do not like what you hear.
