I think that the smile is the most interesting of reactions to get from someone.  A smile can mean so many different things that it is hard to know which one you are looking at when you see a smile.  A smile can mask emotions when someone is confused, nervous, anxious, or sometimes even angry.  A smile can be used to flirt.  A smile can be used when someone is shy and doesn’t know what to say.  A smile can be used by the villain when they are up to something sinister.  A smile can be used to show appreciation.  There are many uses, but I really think that smiles bring confusion.  It is easy to misread a smile. 

I have heard someone say before to never trust someone who smiles a lot.  At the time it seemed strange to me because we are trained to believe that a smile is a welcoming and warm gesture.  It makes most people feel good to see someone smile.  Now I’m not so sure they didn’t have a point.  I guess it depends on the life experiences that get you to a conclusion like what you believe a smile is.
