whay?

Sit and watch with the whole world is so optimistic ... every day there are people who display happiness but with a false smile, the question is why? It really should we pretend? In my case ... everything goes on slipping away, all you touch, everything I say and all they do is like go to all is worse. Why the sun sets and rises once. Begin to think for me there is no place for compassion as long when the world is evil and sneaky ... Do I wrong?
