The beauty of a smile is dependent not on the aesthetics that adorn it, but rather on the magnitude of pain and the sadness through which it has struggled to shine.
The value of a smile is accentuated when it is provided to someone who, despite their inner turmoil, harbours a feeling of loneliness and hopelessness which, on the receipt of such a smile, manages to smile back in return.
A smile serves its best purpose when it shines through despite circumstances and events that might seek to keep it hidden.
