A smile is an interesting thing.  Because it means different things to different people and in different situations.  If you smile at someone walking down the hallway, you do it to be polite, unless of course they are a good friend and you are genually happy to see them.  If you smile during an interview, it's because you want the interviewers to like you and think that you are a happy and positive person who can do great things for their company.  My mother is a very happy person with a very positive mindset.  She smiles constantly, even when she may be having a tough day, basically because she cares about people and doesn't let herself get wrapped up in her personal problems. 

So why do you smile?

Think about how much you smile every day.  And when.  How do you feel when you smile?  Is it genuine, or fake?  Are you doing it just to be polite and to make people think you are happy?  Some people believe that if you smile enough, even when you are sad, you can actually change your mood from a negative to a positive one.  I don't know about that, but maybe we should all try it once in a while. 

Michael Jackson's favorite song was "Smile" by Charlie Chaplin.  The lyrics tell us to smile even when our hearts are breaking.  Some people may look at this song and think, "why would I want to cover up my real emotions?  I'm not afraid to show people that I am sad or angry.  People who are happy all the time are just fake."  If you continue to listen though, you'll see that smiling actually gives you a little bit of hope, that "life is still worthwhile if you just smile."  Can a smile expel the darkness like Harry Potter using a patronus charm to scare the dementors away? 

We'll just have to find out!  :0)
