Faces

For show,
Faces,
On the wall.

Our faces, with the help of the muscles help express our emotion. Frown if you disapprove and smile if you are pleased; but don't force anything because emotion in the face can be read. I suppose even a child can tell if a smile is genuine or fake. When it is not real, perhaps you'll just lose it, your face that is; which means you'll get humiliated and less respected.
