Simple acts of communication can establish and maintain friendly relations in people. Communicating effectively is not just a matter of being able to express oneself, it also means that one considers that the overall impression is conveyed correctly, and he/ she is aware of the emotion behind the information being expressed.
Using greetings plays a key role in the process of interacting with others to form and maintain friendships. Greetings like ‘hello’ and ‘goodbye’ add politeness to the communication. These are one of the basic functions of communication. A ‘hi’ or a ‘hello’ opens the door for conversation between people. Saying a ‘goodbye’ or ‘see you’ signals temporary farewell; it sets the stage for having another conversation with the other person the next time you meet him/ her. Similarly, saying a ‘thanks’ to someone, shows the politeness of the speaker.
