The smile is a very important feature of the human face. But because of human intelligence, even that good part of human nature can be used in the wrong way, such as sarcastic or diplomatic smiles, which only serve to create suspicion. I feel that a genuine, affectionate smile is very important in our day to day lives. How one creates that smile largely depends on ones attitude. It is illogical to expect smiles from others if one does not smile oneself. Therefore, one can see that many things depend on ones own behavior.
