Smiling at a stranger. (The worth of smile)

We need great courage when we brightly smile at a stranger who we don't know at all.

Because we cannot predict what he or she would react.
Our smiles can be either accepted or ignored.

Smile is deeply connected to our soul.
So, smiling at some person is an active behavior of delivering the light of our soul to another people.

It is not the action which is possible when our mind is closed or we have lost our faith for the people around us.

The society which knows the value of smiles and the smiling people are those worth living in.
