A Smile  

What does Smile mean? form one's features into a pleased, kind, or amused expression, typically with the corners of the mouth turned up and the front teeth exposed.

I really like this quote a lot because its meaning you have to enjoy smiling if you don't smile then whats the point of even being born the first thing people see in you is your smile they can tell if your a happy person or your not so therefore i believe that you should always smile and let others talk.
