SMILE...the most mysterious and confusing expression that has ever been created, because we don't realy know what's beyond that SMILE. We don't know whether the person is realy happy or just hiding her/him true emotion by it. We can even make people SMILE just by SMILING back to them. But on the other hand, we can also make them fool by not showing them our real feeling just by "SMILING".
Just going to SMILE like nothing is wrong, talk like everything is perfect, act like its just a dream and pretend like its not hurting us.
