Two wrongs don't make a right. But three rights make a left.

            A smile painted on a plaster face
            is sad as sad can be,
            she hides it well but I can tell
            she's doing it for me.

            The hurt inside can't be denied
             but no-one wants to see,
             the upset, the sadden look,
             the painted smile is on for me.

             The colourful smile only last awhile
             we see beneath the paint.
             It's not the same but who's can blame
             there is no plaster saint.
