A smile can mean numerous things. 1 you seem happy, 2 you appear friendly and 3 you might be in cloud nine. But a smile can always be acted out. No one really knows what`s hidden behind that one particular smile. Maybe it`s hurt, anger, devastation, sadness or even just simple annoyness. It is really easy to fake a smile, you don`t want others to know what you`re really going through. I for one, often do.
