Touching or rubbing the nose is one of the most common self-touching gestures, which is usually done by people who are lying or trying to hide something. Blowing of the nose is a gesture seen as rude by most countries, but it is considered as healthy in some countries in Asia.
Licking or biting the lips is one of the typical signals of flirting done by women. Kissing is a gesture to show one's affection, and also used as a form of greeting. But there are conservative countries, particularly in Asia, which do not allow public display of affection such as kissing. And in some cultures like in the Philippines and Puerto Rico, the lips are used for pointing instead of the finger.
Arms And Hands
There are plenty different hand gestures, and each one has different meanings. The most common hand gestures are hands-in-the-pocket, arms crossed over the chest, hands on the waist, and handshakes. The first one may indicate nervousness or lack of interest. Crossing the arms signifies a defensive posture, and it may also mean doubt or suspicion of what the other person is saying. The hands on the waist may indicate anger or fury, but men also do this to show their masculinity. A handshake, meanwhile, is a form of greeting in most countries.
Legs And Feet
Crossing the legs are done by most people, especially women. Most of the time, it is done as a comfortable position. However, there are countries that regard this action as rude.
The Misuse Of The Ability
The ability of reading someone's body gestures sometimes is not reliable. The gestures performed by a person that are regarded as rude by other people maybe just habits of that person without the intention of being rude.
