A word can mean many things 
They can move mountains
They can move the hearts of people
One word can give a person a reason to smile 
That smile is a thousand words in one 
A word can bring a tear to your eye
This one tear could bring love and comfort 
Your words could be hurtful and could bring pain
A word could make you think 
A word could bring back a memory 
Speak 
Use your words to say what needs to be said....
