Greeting is an act of communication in which human beings intentionally make their presence known to each other, to show attention to, and to suggest a type of relationship (usually cordial) or social status (formal or informal) between individuals or groups of people coming in contact with each other. Greetings are sometimes used just prior to a conversation or to greet in passing, such as on a sidewalk or trail. While greeting customs are highly culture- and situation-specific and may change within a culture depending on social status and relationship, they exist in all known human cultures. Greetings can be expressed both audibly and physically, and often involve a combination of the two. This topic excludes military and ceremonial salutes but includes rituals other than gestures.
A greeting can consist of an exchange of formal expression, kisses, handshakes, hugs, and various gestures. The form of greeting is determined by social etiquette, as well as by the relationship of the people. The formal greeting may involve a verbal acknowledgment and sometimes a handshake, but beyond that, facial expression, gestures, body language, and eye contact can all signal what type of greeting is expected.[1] Gestures are the most obvious signal, for instance, greeting someone with open arms is generally a sign that a hug is expected.[2] However, crossing arms can be interpreted as a sign of hostility. The facial expression, body language, and eye contact reflect emotions and interest level. A frown, slouching and lowered eye contact suggests disinterest, while smiling and an exuberant attitude is a sign of welcome. Many different gestures are used throughout the world as simple greetings. In Western cultures, the handshake is very common, though it has numerous subtle variations in the strength of grip, the vigour of the shake, the dominant position of one hand over the other, and whether or not the left hand is used. quas.
