How can one smile such sweet smiles,
When life brings me nothing but tears,
Smile is a sing of care
I smile when I am sad

I need a smile to glitter my wolrd,
Smile is a magic, brings hearts together
Every smile has a rhyme
A smile is a thousand words

Smile when you see no reason for living
Smile for the good things in life
It makes your moment precious
Smile is the essence of life.

Maria Luisa Taylor
